painful sex?

Alright I cant be the only one right? Im 21 weeks pregnant and the last week it has been painful to have sex! No matter what position we are in and no matter how much lube I slather on there, I still get this like sharp pain? But it feels like its more towards my clit? Some positions are better than others, but the thought of sex has me totally turned off. I cant keep grinning and baring it anymore! Please tell me this is normal?
