So, you would not have pregnancy
symptoms or know you were pregnant three days post unprotected sex. Keep that in mind. And a
pregnancy test would not be accurate at all. The earliest you can get an accurate pregnancy test result from a home test is 2.5 weeks after the unprotected sex. You may be having an off period. This does happen. It can happen out of nowhere. A hormonal shift can happen at any time and wham, our period is funky from how it normally is.
