Is it possible to feel pregnancy symptoms two days after sex? or is it pms symptoms because period due soon?

Unlikely pregnancy: It is unlikely that you would feel pregnancy symptoms that early. Could be PMS but if you miss a period please check a pregnancy test. If you are having unprotected sex please take a prenatal vitamin with folate (folic acid) to prevent birth defects if you do become pregnant.

Unlikely: It may be feelings of optimism. Implantation has not likely even occurred. All the best in achieving your result.

It's possible: It may not be common, but it is possible. Some women can be very sensitive to the fluctuation in hormone levels caused by pregnancy, and even after 2 days, symptoms may be evident in those women. If you miss your period, then check a pregnancy test.

Unlikely: 2 days after sex is probably too early. Implantation occurs much later
