Pain during sex and pregnancy? Do they related?

Nurfateeha

Hai guys. Im on TTC and today is my 10 Dpo. I have a dew simptom tht i never felt before. I also did a pregnancy test on 7&9 DPO. Negative on 7 Dpo, and i guess i saw a VVVVFL on 9 Dpo. I had a sex with my husband that night but its not like usual. I felt not comfortable and pain during sex. We end the session due to my pain. Can anyone share anything their experience bout this? What actually happen? Is it dangerous?
