so me and my boyfriend had sex towards the end of my period (i was still kind of on it, i’m also on birth control) so this was around January 28th or so. i was just ending my period so i wasn’t that wet and (TMI) he was going really hard, harder than usual. ever since then, every time i receive any penetration (fingering, etc) i bleed. it’s a light bleeding. i don’t bleed other than if something was inserted. but it looks like implantation bleeding. today is the 7th. i am experiencing extreme cramping. do i have lacerations in my cervix? do i need to take a test? i’m extremely worried! i’ve been on birth control for almost a year now.
