Hi I'm 19, and I'm very confused. Every month my period is on time and heavy with cramps. This month I was 4 days late and on the fourth day I had light bleeding. Exactly 6-12 before the bleeding started me and my boyfriend had unprotected sex. I've never had a light period before. This has been going on for about 4 days and it's the same light bleeding with clear disharge. I feel constantly bloated since the day my period was suppose to start. What is wrong with me????
