This might be a bit TMI, sorry. I'm 22 weeks pregnant and as I was masturbating earlier I accidentally touched my cervix and I'm almost certain I could have put one finger in. Also the tissue seemed a bit...idk, frayed? The moment I realised I pulled away and stopped, knowing thats how you measure dialation (1 finger=1 cm), thats how you get bacteria in, and that I could do some damage. Question is how normal is this, has it happened to anyone and, most importantly should I contact my doctor? From what I've read it could be bad, but am I just panicking?

This is my third pregnancy, had one miscarriage at 8 weeks and have a two year old at home. Also, I'm insanely horny all the time, so we have sex/I masturbate at least once/day amd it is more rough than not. I have cramps all the time (but I think it's getting better ince I've started drinking Mg) Also, the baby is active, I feel her right now :)

EDIT: Contacted my obgyn, have an appointment for tomorrow :) Thanks y'all
