Up and down libido!?!

Aaliyah
I used to have a veryyy high libido like almost annoying, I wanted sex 24/7, I was very kinky and passionate. I started having sex at 15 though, not very frequent though until I was 16. Well I was sexually assaulted at 16 as well and it makes me very uncomfortable thinking about because I can't forgive myself I guess, it's really a crazy story but I just feel like it was my fault. Well so anyways I met my SO Then and we were sexually active, and my libido was normal for the most part until I got on the Depo, then my libido was so low I was just completely uninterested so after 6 Months I stopped getting it. Well then my libido went up eventually afterwards and it was really high, like I wanted sex everywhere, anywhere and all the time. 2 years past. Then I guess I thought more about my past and was disgusted, sex felt wrong and so I didn't want to, I just pleased my SO so I wouldn't have to keep bringing it up because it made him angry that I never said anything to anyone. Long story short we became pregnant and my libido went up, hormones I suppose...well now I'm 13 weeks PP and some days sex is disgusting and some days I'm dying for it. How do I fix this? Is it just hormonal??? Am I normal? Help!?!
