Sex drive is through the roof 😅

So, I've never had much of a sex drive. I do blame it on a bad previous relationship and also my previous birth control killing my hormones, so when I had it removed I thought it would bounce back.. Well it didn't.. Until I ovulated (but then I don't know if that's cos I wanted to get pregnant so bad that that played a part).. Well I'm 19 weeks tomorrow and for the past week... All I've wanted is sex and lots of it😂 this morning at 5am I WOKE MY HUSBAND UP to have sex.. Never in the 5.5 years we've been together have I done that 😂

I'm absolutely petrified that my drive is going to dissappear again, anyone else been through similar?
