Hi,3 weeks ago on a Saturday night April 2,I had sex with my bf and was bleeding after. The next day was just spotting. And it stopped. After 5 days (Saturday April 9) I started to bleed again,thought maybe I was on my period but it's kinda weird coz blood didn't really come out,spotty kinda til the next day and on a Monday (April 11) started to bleed which I was pretty sure I was on my period and lasted til the 16 Saturday. I went to see a doctor and he gave me antibiotics macrobid for 7 days and I don't think it helps coz I noticed blood in my pee. And yesterday Monday 27, I didn't feel good,had a headache,back pain. I'm still on the antibiotic. I only have one kidney and Im scared. I also noticed bruises on my left leg last wk. I used to get them before and during my period but now it scares me. Pls help. Will go see a doctor on Saturday. Thanks
