This might sound crazy but I think I am pregnant. But I want to know if anyone else experienced symptoms this early or even if it’s possible. So this would be anywhere from a week to 3 days after sex (these are the 2 times I had sex I’ve been experienced extreme moodiness way more than a normal level. But what really made me think I am is out of nowhere I got extremely nauseous like I was going to throw up ( completely reminded me of how I felt when I was pregnant). I’m still a week and a half from when my period is due so don’t know if it would show on a pregnancy test. But my question is, is it possible to have symptoms a week or 3 day after having sex if you are pregnant? Has anyone else ever had symptoms this early?
