Trying to conceive

Maleesha

Me and my boyfriend jus tried to conceive like 2 weeks ago when I was fertile and when I say going at it I really mean going at it. He came in me every time. But recently we were going at it and afterwards he noticed I was bleeding. But it was faint and the very next day I started bleeding like my period and my periods are heavy and then this morning nothing. No blood no spotting. Please can someone help me understand?
