Pain during sex while pregnant

Julia • I'm just a girl living in a world full of hate
Im 7 weeks and 1 day pregnant since I've found out I was pregnant I've been having these pains in my vagina during sex I also get terrible cramps and have to caught cut the love of my life off which I don't want to do I don't know if it's from the Kegel muscle exercise I do everyday or from swelling does anybody else have this problem or did they when they were pregnant
