I’ve been stressing about if I could be pregnant and that’s been messing with my head recently this week I took a pregnancy test that came out negative oh and btw I took first response and it came out negative I took one at night and another one in the morning they both came out negative while I was on my period which I started on Monday and ended today and I had brown discharge which I have at the end of my periods , do you guys think it’s the stress cuz everytime I’ve done it I’ve always used protection every time
