So I'm not supposed to start my period till 6 days from now but this morning I woke up and I was bleeding a lot and the blood is thinner than my usual period blood and so I looked up reasons why and one of them was that sometimes when a fertilized egg attaches to the uterus it caused spotting. and this would happen 6-12 days after conception which would make sense because I had unprotected sex 9 days ago. I'm going to my doctor tomorrow to get checked out but my question is has this happened to anyone else? could my period just be starting early?
