Hi I have had unprotected sex and the guy went in me. I am on birth control but I did have sex around my ovulation time and now I am getting this weird fluttery feeling in my stomach and getting headaches and my stomach is bloating a lot and is extra hard when it s bloated which is not normal for me. I also have been gettig a lot of headaches even a few migraines. Could I be pregnant? My period is suppose to come in a week.
