My period has been really strange. My sons 5 months old and the other day I woke up puking instantly like I used to with him. Well I have been bleeding but i only bleed in the mornings the last 3 days and then by the afternoon I've stopped. It makes no since it's not heavy like usual and I started 5 days early. Anyone ever had this happen to them? Could I be pregnant? I take my birth control pills everyday at 3 pm...
