Idk what to do..

Megan • I'm 20 years old, born on April 30th. I have a baby girl named Lauryn who was born on October 7th and means everything to me ♡ ♡ I have been in a relationship for 3 years and counting :)
Every time I have sex it hurts so much. I'm not new to the sex game lol far from it actually. Anyways it was like this in the past too. I have a child now but it was bad before having her too. We use lube but it doesn't help. Any idea how to help or what could be wrong?
