So around October 14 my period started and on Monday 17 I had sex and then my period stop and I’m not sure if it’s my period because it came out lightish brown and it slowly went away around Thursday 20 or Wednesday. After that the past few days around the 21rst and 27th I had unprotected sex and I asked my bf if he came in me and he said he did because he puled out late once. And also one time when I was giving him head around the 21rst through the 27th he came in my mouth and I didn’t put the cum inside my vagina I just rubbed it in there. And on november 2nd we had sex again but he said he couldn’t cum at all. And for the past weeks I haven’t gotten an appetite at all and i feel more sad and more tired especially cause I work but even before that I was getting more tired. I felt nauseous sometimes but not as often. I have diarrhea all the time when I use the restroom. And I think sometimes my pee is foamy and my stomach and uterus been having some pain. Usually my period is irregular so idk when to take the test because yesterday I took one and it came out negative so idk what to think or so rn I just need advice rn.
