So I am on birth control. I typically take it between 9-9:30, I’m really good at taking 9:30 everyday. And I had unprotective sex once back in beginning of March. I took pregnancies test less then week ago and it came back negative. I have been throwing up here and there but I think it’s due to stress and anxiety I have been having. But my period still haven’t came yet for my birth control and I’m on like my 4th sugar pill. Should I take another test if comes back negative start my new pack if I don’t get my period by today?
