Hi , I've been on the mini pill for 2 and a half years and I recently stopped since my husband and I are trying to conceive .. i had a three day bleeding with blood clots then last month a normal period .. My husband came in me twice and I've been having lower back pain , craving for food I don't eat , breast hurts a little , headaches/ light headed . Pressing on the top of my stomach feels so uncomfortable.. I took many pregnancy test and they all came out negative.. Could I be pregnant ?
