I had protected sex three times the last day of my period and it hurt when my boyfriend went deep. Like a stabbing pain in my right side and pelvis.That was Friday night-Saturday morning and now it s ten o clock Sunday and from about 3:30 am and still continuing, I have had pain while urinating. Not when it touches the vagina, but when I finish peeing. Also a few hours ago I started to bleed while urinating and feel like I need to go a lot. Could it be an std, because we had unprotected sex a few months ago too? Or is it possibly a UTI or something else?
