OK so my boyfriend and I had unprotected sex maybe about a month ago. And since then I have had more frequent urine, I've been really tired all the time, I've been getting headaches a lot more, my eating habits have changed a little bit I'm not hungery as much as I used to be, and about a week ago I had this weird period that only lasted a day, and I just contstintly feel bloated... I don't know if its just me cause I'm nervous or not but I'm supposed to hit my period this week but what kind of syptoms would I be experiancing in the first month?
