Hi Im currently on a xulane patch and today is the day I take it off because my period suppose to come this week. But I had sex last night and ever since I woke up I been rushing to to restroom feeling like I have a full bladder but when I pee it s only a little that comes out and it also hurts while peeing but once I wipe it s like a pinkish blood on the tissue is it because I might be pregnant or because my period Is coming ?
