Odd Pregnancy Symptom

Rochelle
Okay Ladies,
It's been 13 years since I have gone through a full term pregnancy and I was a lot younger than I am now. I have this random pain in my VJJ that feels like I have had rough sex for a weekend. No really cramping or discharge, but I have to sit down gently because she is sore....and we are abstaining from sex until week 6 because of a previous miscarriage I had a while ago. 
I vaguely remember random pains, but maybe this is why I stopped having babies after my 12 year old.....oh I am just about 4 weeks pregnant.
