The probability of becoming pregnant two days after ovulation?
If my girlfriend has regular menstrual cycles, what is the likelihood of pregnancy if we had unprotected intercourse two days after ovulation? The app indicated a moderate chance, but I'm still concerned.
Is ovulation day always accurate?

More Info
When considering the chances of pregnancy two days after ovulation, it's essential to understand the timing of ovulation and the lifespan of both sperm and the egg. Ovulation typically occurs about 14 days before the start of a woman's next menstrual period, and it is during this time that the egg is released from the ovary and is available for fertilization. The egg has a relatively short lifespan of about 12 to 24 hours after ovulation. In contrast, sperm can survive in the female reproductive tract for up to five days, depending on various factors such as the quality of the sperm and the conditions within the reproductive tract.
Given that your girlfriend has a regular menstrual cycle, predicting ovulation can be more accurate. If she ovulated on a specific day, having unprotected intercourse two days after ovulation would generally be considered a lower-risk time for conception, as the egg would likely no longer be viable for fertilization. However, if ovulation occurred later than expected, or if the sperm were to survive longer than average, there is still a possibility of pregnancy.
The software you mentioned that indicates a "medium" chance of pregnancy likely takes into account various factors, including the timing of intercourse relative to ovulation, the regularity of the menstrual cycle, and the health of both partners. It's important to note that while ovulation prediction methods can be helpful, they are not foolproof. Factors such as stress, illness, and hormonal fluctuations can affect the timing of ovulation.
If you are concerned about the possibility of pregnancy, it may be beneficial to wait until your girlfriend's next expected period to take a home pregnancy test. These tests are most accurate when taken after a missed period, as they measure the hormone hCG (human chorionic gonadotropin), which is produced after a fertilized egg implants in the uterus.
In summary, while the chances of pregnancy two days after ovulation are generally lower, they are not zero. If you are looking to avoid pregnancy, it is advisable to use contraception consistently. Conversely, if you are trying to conceive, understanding the timing of ovulation and engaging in intercourse during the fertile window (which includes the days leading up to and including ovulation) can increase the chances of pregnancy. If you have further concerns or questions about fertility, consulting with a healthcare provider or a fertility specialist can provide personalized guidance and support.
