I am 18 weeks pregnant and me and my boyfriend havnt had a lot of sex during pregnancy during to how sick I felt and how tired I was. I finally have my energy back and we keep trying to have sex but it's like my vagina is too tight and it just won't go in without it burning and hurting me so much! We use plenty of lubricant. If we are lucky enough to to get it in i become very soar and swollen, and will hurt for a day or two after?! Can anyone help?
