Sex drive is off since pregnancy, anyone else?

My husband and I used to be very sexually active. Like 3 times a day. Then I got pregnant and changed birth control and my sex drive is off and I am a dessert.

While I was pregnant, it was like a legit desert down there. I felt so bad, my husband would t ry to have sex but I was NEVER in the mood. Then on the rare occasion we did have sex it hurt, every time It felt like when you have sex for the first time.

Fast forward a year after I had our baby. My husband and I have sex about 3 times a week, which is i think is average. But I am still so dry, we always have to use lube. I used to get so wet naturally and I can feel my sex drive being off but idk why. I’m also on Mirena which is the only other thing that has changed.

Comments? Advice?
