I would like to inquire about ovulation issues?
Hello Dr.
Tsao, I would like to ask some questions related to ovulation.
My menstrual period started on March 29, and I took ovulation medication continuously for five days starting March 31, with two pills each day.
On April 11, I went to the hospital for a follicle scan, and the doctor said I had two follicles, one measuring 1.2 cm and the other 0.8 cm, with an endometrial thickness of 6.6 mm.
The doctor advised that I should have intercourse on April 14 or 15.
I returned for a follow-up on April 18 to check for ovulation.
I was concerned that my endometrium might not be sufficient, so the doctor prescribed Estrogen for me, to take one pill daily.
On the afternoon of April 14, I had intercourse, and since I could alternate days to ensure timing with ovulation, I went to another gynecology clinic on April 16 to check the follicle sizes.
The doctor reported that my two follicles measured 1.3 cm and 1.4 cm, and since they were still small, the doctor prescribed more ovulation medication (two Clomid pills and two Tamoxifen pills daily).
When I returned to the hospital on April 18 for another follicle scan, the doctor said I only had one follicle left measuring 1.8 cm, and the other one was gone.
I mentioned that my basal body temperature had risen on the morning of April 17, and the doctor suggested that I might have ovulated.
Therefore, on the evening of April 18, the doctor administered an ovulation trigger shot and advised me to have intercourse on the night of April 19.
From April 17 to 19, my basal body temperature remained elevated, so I would like to ask if it is common to have a second ovulation about three to four days later in a month? Is there a possibility of conception during this second ovulation? Will I miss the implantation window? If I have intercourse on April 19, could it affect the success rate of implantation for the first ovulation? I feel very confused about my entire ovulation cycle, as I have never experienced this before.
Thank you, doctor.

More Info
Understanding ovulation and its implications for fertility can be quite complex, especially when you are actively trying to conceive. Based on your detailed account, it appears that you are closely monitoring your ovulation and following your doctor's recommendations, which is a positive step towards improving your chances of conception.
Firstly, let's clarify the ovulation process. Typically, ovulation occurs when a mature egg is released from the ovary, and this usually happens around the midpoint of your menstrual cycle. In a standard 28-day cycle, ovulation typically occurs around day 14. However, cycles can vary significantly from person to person, and even from month to month for the same individual. Factors such as stress, hormonal imbalances, and medications can influence the timing and occurrence of ovulation.
In your case, you mentioned that you had two follicles measured at different sizes on various days, which indicates that your body is responding to the medications you are taking. The fact that you had a rise in your basal body temperature (BBT) suggests that ovulation likely occurred around that time, as a rise in BBT is a common sign of ovulation due to increased progesterone levels.
Regarding your questions:
1. Can you have two ovulations in a month? While it is rare, it is possible for a woman to experience more than one ovulation in a single cycle, particularly if she is using ovulation-inducing medications like Clomid or Tamoxifen. This phenomenon is known as "multiple ovulation," and it can lead to the release of more than one egg, increasing the chances of conception, especially if both eggs are viable.
2. Is there a chance of conception with the second ovulation? Yes, if you ovulated again after the first egg was released, there is still a possibility of conception. Sperm can survive in the female reproductive tract for up to five days, so if you had intercourse around the time of the second ovulation, there is a chance that sperm could fertilize the egg.
3. Will this affect implantation? Implantation typically occurs about 6-10 days after ovulation. If you had intercourse on April 19, and if ovulation occurred around that time, you would still be within the window for implantation. However, if the first egg was released earlier and you are concerned about its implantation, it is essential to note that each egg's viability is independent. The success of implantation depends on various factors, including the quality of the egg, the uterine lining, and the timing of intercourse.
4. Confusion about the cycle: It is understandable to feel confused, especially with the introduction of medications and monitoring. The hormonal changes induced by medications can sometimes lead to unexpected patterns in your cycle. It’s crucial to maintain open communication with your healthcare provider, who can provide clarity on your specific situation and help you navigate the complexities of your cycle.
In summary, while the process of ovulation and conception can be intricate, your proactive approach to monitoring and following medical advice is commendable. If you continue to have concerns or if your cycles remain irregular, it may be beneficial to discuss further testing or treatment options with your healthcare provider. Remember, patience is key in this journey, and staying informed will empower you as you work towards conception.
