Thoughts/ Opinions

So Wednesday, February 24 I had my period which was one dark brown streak of blood. Thursday, February 25 I had 4 drops of blood. Friday, Saturday, and Sunday I had nothing. I am on birth control (the pill) and I've gotten pregnant from it before. Thursday, February 25 I was puking all day. Now I'm tired, and nauseous all the time. I never thought about becoming pregnant while on the pill for a second time until my friend said something. The earliest time I can take a test is March 7 because I don't want to freak out my boyfriend. I work with children and I could just be sick from whatever germs they carry. I'm not stressed out and even if I was, my period would be medium or heavy. Now I'm just curious what you ladies have to say. Please no judging or rude comments.
