Quoting *~AngelEyes~*:" That's another thing that came to my mind. I haven't had any bleeding from it this pregnancy thank God. ... [snip!] ... my miscarriage. It also sometimes hurts without us having sex. But its not often but it does make my back hurt more than usual."
I also had a miscarriage ..so I freaked anytime I bled. I bled pretty bad around 10 weeks & thought for sure I lost her but they said it was "late implantation bleeding" which made no sense because there was a lot..BUT besides pre-term labor I went on to have a healthy 35 weeker that didn't even go to the NICU
She's perfect. She full on walked by 9 months, talks quite a bit, & will be a year old in couple weeks. So try not to stress about that
As far as the cervix pain even without sex, it's normal. It will get worse as you get further along :/ It's worth it in the end though!
