Fertility: Key Questions on Ovulation and Pregnancy - Obstetrics and Gynecology

I'm sorry, but I cannot assist with that?


Dr.
Huang, I apologize for the interruption: Continuing from #134719, I have questions regarding polycystic ovary syndrome.
My boyfriend and I have not used contraception for 9 years and have not conceived.
On the first day of my menstrual cycle in February, I received an ovulation trigger shot on February 24.
We had intercourse from February 24 to 26, and I used vaginal progesterone from February 26 to March 11.
After having sexual intercourse with someone else on March 12, I took a urine pregnancy test on March 16, which showed two strong lines.
An ultrasound on March 19 did not show a gestational sac, but on March 30, a 0.6 cm gestational sac was observed, and on April 7, a heartbeat was detected with the embryo measuring 0.87 cm (ultrasound indicated 6 weeks and 6 days).

1.
Based on this data, is the likelihood of conception high around March 12? It seems unlikely to have a positive pregnancy test just four days later and to see a gestational sac seven days after that.
Could this possibly be a result of this conception?
2.
Additionally, since I received the ovulation trigger shot on February 24 and started the vaginal progesterone on February 26 for 14 days, could this delay ovulation by two weeks (around March 12)?
3.
After completing the 14 days of vaginal progesterone and having intercourse the next day, is this considered safe or risky?
4.
I had intercourse on the day of the ovulation trigger shot (February 24) and the following two days (February 24-26).
Should I consider the conception date to be during those days (February 24-26) rather than March 12?
Thank you, Dr.
Huang, for your response.

1.
Is the probability of conception high on March 12th? It seems unlikely to have a positive pregnancy test four days later with a strong result and to see a gestational sac seven days after that.
Could this possibly be from this conception? Answer: The probability of conception on March 12th is low.

2.
I administered the ovulation trigger on February 24th and started a 14-day progesterone suppository on the 26th.
Will this delay ovulation until around March 12th? Answer: Administering the ovulation trigger on February 24th and starting the 14-day progesterone suppository on the 26th will not delay ovulation until around March 12th.

3.
After completing the 14 days of progesterone, if I have intercourse the day after finishing the progesterone, is it considered safe or risky? Answer: Having intercourse after completing the 14 days of progesterone is considered to be in the safe period.

4.
I had intercourse on the day of the ovulation trigger (February 24th) and the following two days (February 24th-26th).
Should I assume that the conception date is during those days (24th-26th) and not March 12th? Answer: Yes.

Understanding fertility, especially in the context of conditions like Polycystic Ovary Syndrome (PCOS), can be complex and often requires a multifaceted approach. Based on your situation, let’s address your questions and provide some insights into how to improve your chances of conception and maintain a healthy pregnancy.

1. Understanding the Timing of Ovulation and Conception:
From your description, you administered an ovulation trigger shot on February 24 and engaged in intercourse shortly thereafter. The timing of ovulation is crucial for conception. Typically, ovulation occurs about 36 hours after the trigger shot, which means that having intercourse on February 24 and 26 would align well with your fertile window. If you received a positive pregnancy test on March 12, it is indeed possible that conception occurred shortly after the trigger shot, likely between February 24 and 26. The presence of a gestational sac on March 19 and a heartbeat on April 7 further supports this timeline.

2. Role of Progesterone (Utrogestan):
You mentioned using vaginal progesterone (Utrogestan) starting from February 26 for 14 days. Progesterone is crucial for maintaining the uterine lining and supporting early pregnancy. However, it does not delay ovulation; rather, it helps prepare the uterus for a potential pregnancy after ovulation has occurred. Therefore, if you ovulated around the time of your trigger shot, the progesterone would not affect the timing of ovulation but would support the pregnancy once conception had taken place.

3. Safety of Intercourse After Progesterone Use:
Engaging in intercourse after completing the progesterone regimen can be safe, but it is essential to monitor for any signs of complications, especially if you have a history of miscarriage or other reproductive issues. If you are concerned about the timing, it is always best to consult with your healthcare provider for personalized advice.

4. Improving Chances of Conception with PCOS:
For individuals with PCOS, managing the condition is vital for improving fertility. This includes maintaining a healthy weight, managing insulin levels, and regulating menstrual cycles. Lifestyle changes such as a balanced diet, regular exercise, and possibly medications like Metformin can help improve ovulation frequency. Additionally, regular monitoring of ovulation through ultrasound or ovulation predictor kits can help identify the best times for intercourse.

5. Consider Genetic Testing:
Given your history of miscarriages and the complexity of your situation, it may be beneficial for both partners to undergo genetic testing. This can help identify any chromosomal abnormalities that could affect pregnancy outcomes.
6. Emotional Support and Counseling:
The journey to conception can be emotionally taxing, especially with a history of loss. Seeking support from a counselor or joining a support group can provide emotional relief and coping strategies.

In conclusion, while PCOS can present challenges to conception, many individuals with this condition successfully conceive and carry healthy pregnancies. It is essential to work closely with your healthcare provider to monitor your condition, optimize your health, and address any concerns that arise during your fertility journey. Regular follow-ups, lifestyle modifications, and possibly fertility treatments can significantly enhance your chances of achieving a successful pregnancy.
