Pregnancy date?


Question 1: Can having sexual intercourse on August 30th lead to pregnancy? (My period started on August 25th, and it was the sixth day of my cycle, almost ending, and we used a condom the entire time without ejaculation.)
Question 2: What would be the date of conception? (My period was supposed to start on September 25th but did not.
My menstrual cycle is usually about seven days late.
I had some bleeding on October 12th and 13th, which I thought was my period, and I was unaware of my pregnancy at that time.
I found out I was seven weeks and three days pregnant during my visit to the obstetrician on November 7th, and my due date is June 23rd.)
Question 3: How long does it typically take to achieve a successful pregnancy?

Dr. Zhang Kunmin reply Obstetrics and Gynecology


Hello, based on your description, due to the irregularity of your cycle, it is possible that conception occurred approximately five weeks before November 7.
The other time points are more difficult to estimate.
Please consult your physician for further evaluation.
Thank you! Wishing you peace and health.
Dr.

More Info


Understanding pregnancy dates can be quite complex, especially when considering factors such as menstrual cycles, ovulation, and the timing of sexual intercourse. Let's break down your questions to provide clarity.

Question 1: Can intercourse on August 30th lead to pregnancy?
Given that your menstrual cycle started on August 25th and you mentioned that it was the sixth day of your period, the likelihood of becoming pregnant from intercourse on August 30th is quite low. Typically, ovulation occurs about 14 days before the start of your next period, which for a regular cycle would be around day 14. Since you were still on your period on August 30th, and assuming you have a typical cycle, it is unlikely that you would have ovulated yet. Additionally, you mentioned that you used a condom, which further reduces the risk of pregnancy, provided it was used correctly and did not break.

Question 2: What is the estimated conception date?
You indicated that your next period was due on September 25th but did not arrive. You also experienced some bleeding on October 12th and 13th, which you initially thought was your period. However, since you later discovered you were pregnant during a visit to the obstetrician on November 7th, it is likely that the bleeding you experienced was implantation bleeding rather than a menstrual period. Implantation bleeding can occur when the fertilized egg attaches to the uterine lining, typically around 6-12 days after conception. Given that you were found to be 7 weeks and 3 days pregnant on November 7th, this would place your estimated conception date around mid-September, likely around September 10-12, depending on your cycle's length and ovulation timing.

Question 3: How long does it take to successfully conceive?
The time it takes to conceive can vary widely among individuals. Factors such as age, health, frequency of intercourse, and timing in relation to ovulation all play significant roles. For many couples, it may take several months to conceive, especially if they are not timing intercourse around ovulation. Generally, if you are actively trying to conceive, it is recommended to have regular intercourse during the fertile window, which is typically the five days leading up to and including the day of ovulation. If you have concerns about fertility or if you have been trying to conceive for over a year without success (or six months if you are over 35), it may be beneficial to consult a healthcare provider for further evaluation.

In summary, based on your provided information, it seems unlikely that intercourse on August 30th would lead to pregnancy, and your estimated conception date is likely around mid-September. If you have any further concerns or questions about your pregnancy or reproductive health, it is always best to consult with a healthcare professional who can provide personalized advice and care.
