If you’ve had unprotected sex, or if you have concerns about pregnancy, consider the actual timeline for conception. Pregnancy symptoms arise from implantation of the embryo into the wall of the uterus — something that takes anywhere from 5 days to 2 weeks to happen after sex. So any symptoms you feel a couple of days after sex are unlikely to be due to pregnancy.
For most females, the first sign of pregnancy will be a missed period. Thereafter, the most common symptoms are nausea (at any time of day), breast tenderness, sleepiness and an increased need to urinate. These usually develop after a missed period, though some people do not experience these symptoms at all.
If you are concerned about a pregnancy, the best way to tell if you’re pregnant is by taking a pregnancy test AFTER your missed period.
