Painful sex

Annelise • Mom of 5
I'm 11weeks we have only had sex 4 times since we found out because I really haven't been in the mood. Tonight for his bday we had sex an omg it hurt. Does this have anything to do with not having sex for the last 3 weeks? Or does it have to do with the baby? I'm going to see my midwife tomorrow for a flu shot so I will definitely ask her. Just curious if anyone else has experienced this or know what may be going on.
