Chance of conception


Hello, doctor.
My last menstrual period started on December 22 and lasted for 4 days.
Prior to that, I visited the hospital to obtain ovulation medication, which I started taking on the third day of my period for a total of 5 days, finishing on December 28.
On January 3, I returned to the hospital for a follicle check, and the ultrasound indicated that I would likely ovulate around January 8 (while my menstrual tracking app indicated January 5 as the ovulation day).
I had intercourse on January 5, and then again on January 7, 8, and 9, which were close to the doctor's estimated ovulation days.
After intercourse, I placed a pillow under my hips.
On the morning of January 15, I took a pregnancy test (using first morning urine), which showed negative.
Is this testing time too early? What is the likelihood of conception? Would you recommend waiting a few more days before testing again? The doctor has prescribed ovulation medication for after my next period, and I will return for another follicle check.
Could you please advise on what steps I can take to increase my chances of conception? Thank you.

Ms. Chen, 20~29 year old female. Ask Date: 2020/01/16

Dr. Cao Guotao reply Obstetrics and Gynecology


Hello, a pregnancy test is usually reliable about 12 days after intercourse.
You can then monitor the situation.
If you want to conceive, please continue to follow up with your original obstetrician for examinations.
Wishing you good health.

More Info


Understanding fertility, ovulation, and the timing of pregnancy testing is crucial for anyone trying to conceive. Based on your timeline and the details you've provided, let's break down the key components of your situation and provide some guidance.


Timing of Ovulation and Intercourse
You mentioned that your last menstrual period started on December 22, and you took ovulation medication starting on December 25. According to your ultrasound, ovulation was expected around January 8, which aligns closely with your app's prediction of January 5. You had intercourse on January 5, 7, 8, and 9, which is excellent timing as sperm can survive in the female reproductive tract for up to five days, making it possible for sperm to be present when the egg is released.


Pregnancy Testing
You conducted a pregnancy test on January 15, which was about a week after your expected ovulation date. Generally, it is recommended to wait at least until the first day of your missed period to take a home pregnancy test for the most accurate result. Since your menstrual cycle is typically around 28 days, if you have a regular cycle, your next period would be expected around January 19. Testing too early can lead to a false negative result, as the hormone hCG (human chorionic gonadotropin), which is detected by pregnancy tests, may not be at a detectable level yet.


Recommendations for Future Testing
Given that you tested on January 15, it would be advisable to wait a few more days and test again around January 19 or 20. If your period does not arrive by then, testing at that point should yield a more reliable result. If you continue to receive negative results but still do not get your period, consider consulting your healthcare provider for further evaluation.


Increasing Chances of Conception
To enhance your chances of conception, consider the following strategies:
1. Track Ovulation Accurately: Continue using your ovulation tracking app and consider using ovulation predictor kits (OPKs) to pinpoint your fertile window more precisely.

2. Optimize Timing: Aim to have intercourse during your fertile window, which is typically the five days leading up to ovulation and the day of ovulation itself.
3. Healthy Lifestyle: Maintain a balanced diet, engage in regular physical activity, and manage stress levels. Avoid smoking and limit alcohol consumption, as these can negatively impact fertility.

4. Consult with Your Doctor: Since you are already under the care of a physician and taking ovulation medication, keep an open line of communication with them. They can provide personalized advice and may suggest further tests if you do not conceive after several cycles.

5. Consider Timing and Frequency: Having intercourse every other day during your fertile window can also be beneficial, as it ensures that sperm is available when ovulation occurs.

6. Review Medications: Discuss with your doctor the medications you are taking and their potential effects on your fertility. Ensure that any medications are appropriate for your situation.


Conclusion
In summary, your timing for intercourse appears to be well-planned around your ovulation. Testing for pregnancy should ideally be done after your expected period for the most accurate results. If you do not conceive this cycle, continue to track your ovulation and maintain a healthy lifestyle while working closely with your healthcare provider to optimize your chances of pregnancy in the future. Remember, conception can take time, and it's important to remain patient and positive throughout the process.
