Low sex drive

Hey guys idk if anyone else went through the same thing but , me and my fiancé have been going out for about 4 years, in the beginning I use to get super wet as he touched me . Now it like I have no sexual desire . And trust me I want sex. I don’t know what’s wrong . And I know I’m attracted to him , he’s mad sexy to me. Last year I went to the doctor because my period is very irregular then I found out I had cysts. Just recently I found out my testosterone levels are very high, and that I have some thyroid problems. Could that be why? Has anyone expierienced this before ??!
