Hi

My situation is that I was on birth control and I had breakthrough bleeding less than a week after my period. It was heavier than my usual flow and lasted longer.
My doctor suggested that I stop the pill, until the bleeding stops. Furthermore, I did and then I started again. I had unprotected sex right after. My problem is my
Period hasn't come yet this month it is 5 days late. I took a pregnancy test it was negative. I took it before my missed period.My question is, "Is this normal or am I pregnant" ?
