I am on birth control pills and have been for the past year. I had unprotected sex last saturdy (my first time after 6months of not doing it). My bf did not cum inside me. I got my period when I was supposed to, which was a couple of days ago. But today, especially, I've been urinating a lot more frequently, but only today. I know that frequent urination is a sign of pregnancy. And I'm wondering, is there a chance to be pregnant, even if you get your period when you're supposed to?
