I think I touched my cervix...? TMI

So I was going to the bathroom and I had my fingers inside to one check my CM to see if i had started my period yet since I'm suppose to Thursday (I'm on birth control) and two because I had unprotected sex and i hate the feeling of cum so I was trying to get it out from hours previous.

I had touched something very hard and pointed in the inside of my vagina. It was pretty low though. I asked my boyfriend and he said he's always felt it and he thought it was my g-spot. I don't really masturbate/ finger myself anymore so I don't notice it.

Google said if your cervix is low and hard it means you're going to get your period/ not ovulating
