I'm quite small and sometimes if my partner gets a bit rough it really hurts if he pushes on my cervix. I'd have this every month a day or so before my period normally but now I'm only 4 weeks pregnant I am concerned that if he's too rough he may cause a miscarriage if he damages my cervix or that plug.

the best thign to do is to tell your partner that you are very sensitive now as you are pregnant. and its very uncomfortable with the force
you'll be able to tell him now without being afraid that you are hurting his feelings. he'll understand and he'll want to be as careful as you are pregnant, hope fully he'l get used to not applyin such pressure an after you have the baby, it will stay this way

i don thtink your partner couldharm the baby as the uterus is desgined ot pretect it!
