I had a bleeding three days after my menstruation. I'm taking birth control pills and forgot to take it for 4 days. I had an unprotected intercourse with my husband on the 2nd day I forgot to take pills. My menstruation was very light and lasted for 6 days. My bleeding is quite heavier than my usual period. What could be the reason? Is there a possibility that I could be pregnant? Please help, I need answers, I'm scared.. this is the first time that I'd experience bleeding in between my period...
