Should I Postpone MMR Vaccination After a Miscarriage? Measles Titer Indicates No Immunity Despite Recent Booster
I am a 34-year-old female, standing at 5'10" and weighing 140 pounds. I take prenatal vitamins as part of my routine and have a history of post-infectious IBS. Recently, I experienced a miscarriage at five weeks. During a visit to my OB, my measles, mumps, and rubella (MMR) titers were evaluated, and the results indicated that I am not immune to measles. It is puzzling because, alongside my regular childhood vaccinations, I received a MMR booster more than two years ago after my first pregnancy. Could it really mean that I lack immunity? Also, would receiving another booster benefit me in this situation? Additionally, my OB advised that I should hold off on getting the booster until my hCG levels return to zero. This guideline confuses me, as I would prefer to act sooner, particularly since it would be necessary to wait a month post-vaccination before attempting to conceive again. Is there a valid reason for this waiting period?

It's understandable to seek clarity on vaccination timing following a miscarriage, especially when it involves your health and future family planning. Here are the key points to consider regarding your MMR vaccination and the recommendation from your OB-GYN.
Main Points:
- MMR Immunity - Your titer results showing no immunity mean that you may not have sufficient protection against measles, despite previous vaccinations.
- Timing of Vaccination - Your OB-GYN's advice to wait until your hCG levels return to zero before getting the MMR booster is based on ensuring your body has fully recovered from the miscarriage.
Explanation:
-
MMR Titer Results: It's not uncommon for some individuals to demonstrate low or no immunity despite having received vaccinations. This can occur due to various factors, including individual variation in response to vaccines. It's crucial for your health and any future pregnancy to be adequately protected against measles, as it can lead to severe health complications.
-
Waiting for hCG Level to Return to Zero: The recommendation to wait before getting vaccinated is precautionary. This allows your body to stabilize and minimizes any potential confusion in symptoms or reaction to the vaccine as your body processes the recent miscarriage. It also ensures that if you are to conceive again soon, you won't have to deal with the overlapping effects of a vaccine and early pregnancy.
Next Steps:
-
Monitor hCG Levels: Follow your OB-GYN's advice and monitor your hCG levels. This will provide clarity on your recovery.
-
Discuss Vaccine Timing: Once your levels return to zero, revisit the topic of vaccination with your OB. Ask if there are specific guidelines on the optimal timing post-miscarriage for the MMR booster.
-
Consider Future Plans: If you are planning to conceive again, confirm with your OB when it is appropriate to resume trying after receiving the booster (usually advised one month post-vaccination).
-
Stay Informed: Keep asking questions and gathering information about any concerns you have during this time. It's your health journey, and understanding all aspects of it will help you feel more confident in your decisions.
Feel free to reach out with any further questions or if you need more information on a specific aspect of your situation. Your health and peace of mind are paramount.

Inquiry About Conception Timing
The child arrived on January 19. Throughout the course of the pregnancy, several ultrasounds were conducted, which regularly confirmed the gestational age with measurements taken at 25 weeks, 32 weeks, and 36 weeks on various occasions. These assessments led medical professionals to approximate the ovulation and fertility period between April 8 and April 17. It is well known that sperm can last in the female reproductive tract for about five days. Notably, intercourse took place on April 26, a date that falls beyond the predicted fertile period. Considering the ultrasound results and standard ovulation patterns, could April 26 reasonably be identified as a possible date for conception?
Chest Discomfort with Red Marks
Over the past year, I have developed red patches predominantly on my upper chest and occasionally on my neck. My physician suspects that this could be linked to anxiety. These marks often become painful upon contact and sometimes provoke an itch. Although I’m uncertain if it’s connected, I also experience occasional discomfort in my chest, particularly around the sternum and collarbone areas. I’m concerned that there might be a misdiagnosis and that an underlying issue could be present. Has anyone else faced a similar situation or discovered the underlying cause of their symptoms? I’m a 24-year-old male who does not smoke, consume alcohol, or use drugs.
Is it Safe to Reintroduce Birth Control After a Smoking Break?
A 45-year-old woman has recently quit smoking after a 7-month period during which she also took Effexor. Due to the combination of medication and smoking, she decided to halt her hormonal birth control along with Effexor. Now, with a month of being smoke-free and currently taking Wellbutrin and Vyvanse, she feels confident about her progress and is contemplating resuming her birth control pills, specifically Seasonale. Her medical history reveals no complications such as blood clots, and her doctor initially approved her to restart the medication. However, after further consideration, the physician sought the opinion of an ObGyn for confirmation. The woman is eagerly awaiting feedback from the specialist, ideally before she intends to begin her birth control again this coming Sunday, which coincides with the start of her menstrual cycle. Since Seasonale is designed for extended use, this will already lead to postponing her period by three months, and any delay in resuming the pill could extend that timeline further by another 3.5 months. She notes that the mini-pill may not effectively assist with managing her PMS cravings, making it an unfavorable choice. The woman is reaching out for guidance on the appropriate course of action. Any insights would be greatly appreciated!
Comparing Marina Coil and Hormone Replacement Therapy
Hello, I should mention that I am located in the UK, which may influence the guidance I receive. Approximately 9-10 years ago, I experienced early menopause and began hormone replacement therapy (HRT) about a year later after completing blood tests and an ultrasound. Roughly a year ago, I unexpectedly started bleeding, prompting my doctor to insert a coil, and now I also use Lenzetto spray to deliver estrogen. The coil has worked wonders—no more bleeding. However, after discontinuing Utrogestan (100mg daily), I've had severe difficulties with sleep, increased anxiety, irritability, and noticeable hair thinning and loss, despite my use of minoxidil. I had some leftover progesterone, so I experimented with taking one tablet daily, which alleviated all these troubling symptoms. Sadly, my doctor advised against continuing this approach, claiming it might be harmful to combine it with the coil. For the past several months, I have been struggling with these side effects, and I’m feeling absolutely terrible! What options are available to me? I want to avoid another episode of bleeding, but I can't bear the thought of continuing with only 5 hours of sleep a night, being perpetually on edge, crying often, snapping at my partner, and worsening my hair situation. I appreciate any recommendations you may have! 😊 Age: 51 Gender: Female Height: 5’7" Weight: 11 stone 4 Ethnicity: Caucasian Duration of symptoms: More than a year Location: UK Current medications: Marina coil, Lenzetto, Symbicort, and blue inhaler
Post-Gynecological Examination Discomfort
I underwent some gynecological tests yesterday as part of the process of preparing for pregnancy. During the examination, they performed swabs for various evaluations and completed a transvaginal ultrasound. Since then, I’ve experienced some discomfort during urination. Approximately 22 hours have passed, and I still notice a slight burning sensation. However, I am not experiencing any other pain, whether while wiping or washing with water. Is this a typical reaction? I understand that there may be some lingering sensitivity, but I thought it wise to reach out for clarification. Thank you!
