Ovulation Welcome to prime time for conception! The probability is that you would not get pregnant having sex during your period. Whether you are trying to get pregnant or looking for ways to avoid pregnancy while engaging in sex , a common question is whether or not you can have sex and get pregnant on your period? And don't forget that sperm can survive for several days, so even if you have sex a few days before you ovulate, you could still get pregnant. That's because sperm can live up to five days if it's trapped in fertile cervical mucus. You need to wait several days after you've missed a period before you can do a Clearblue pregnancy test. This would mean that the days right before your period are the safest for having sex without the expectation of getting pregnant. No, it is possible to get pregnant. If you tested early before your expected period , test again when your period is due If you tested on or after the day of your expected period, wait for three days and test again If your second pregnancy test still gives you a 'Not Pregnant' result and you still haven't had your period, you should see your doctor When can I take a pregnancy test? However, because sperm can survive for up to five days, having sex on the days leading up to ovulation can increase your chances of getting pregnant. On a typical cycle that occurs every 28 to 30 days, the fertility window is usually between Day 11 and Day You are not alone if either of these is one of your questions. If one implants in your endometrium, you'll start to see the rise in human chorionic gonadotropin hCG , the hormone measured by home pregnancy tests , within a week. If you are trying to conceive this is a good time to start having sex. As noted above sperm can live 2, 3 and up to 5 days.
