Okay ladies so I went to the dr the other day for a checkup they took a pregnancy test and came back negative well I’m five days late on me period and I am on birth control and take it everyday. I don’t have any symptoms of pregnancy and the last time I had sex will be a month next week

I went and bought a clear blue test today and that also came back negative

I have been having period cramps here and there and I was PMSing but absolutely no blood and idk why!! Any ideas?
