Hello, So last month I miss about a week of my birth control pills. Me and my boyfriend had unprotected sex around that time. When I did continue to take my pills, when I got to my pills that make my period start it didn't come until day 4 on the period pills. Then it was there for about a day and it stopped. It has been 4 weeks since the unprotected sex and I have taken 4 pregnancy tests. All have came back negative. I have not experienced any kind of pregnancy symptoms other than having to pee a lot and I think that may be a Uti but I'm not sure. I am supposed to get my period next Sunday. Am I pregnant or is my period just messed up because I messed up on my birth control pills?
