I don’t know what to do... I’m so scared.

I am 19 I got married in December. Literally days my husband and I started having problems with sex. I was always in so much pain every time. I ended up pregnant in January despite being on BC, In February I miscarried. I decided to remain off BC because I feared in was causing the pain amongst other symptoms. We have been TTC for 4 months with no BFP. Now I’m experiencing the pain again. We have tried using different forms of lubricants with no success. My husband feels like I don’t get wet enough anymore and that I don’t want sex. I just feel so much pain it isn’t pleasurable anymore. I am so scared that something may be wrong with me and I don’t know what to do.
