So I had unprotected sex dec 8 according to my app that was the day that I should’ve gotten pregnant if I was trying . Which I wasn’t necessarily trying to get pregnant . So my cycle was supposed to come the 20th of dec I didn’t get it until Christmas Day. My cycles are usually a week long & super painful. This time by the 26/27 I was completely off. I took a pregnancy test dec 22. There was a very very faint line. However for the last two days I have been crying over the littlest things! And it’s uncontrollable. At this point should I retest ?
