Do you like sex that much what's wrong with me?

Okay so I've been TTC and usually I don't wanna have sex but once a month but all of a sudden I just wanna have sex all the time my husband loves it. I'm always so tired but also horny at the same time Ive had some cramping since my AF stopped like idk what it is and out of no where yesterday I was eating and had got so horny and ended up getting wet and I was just like wth is this and sex is 1000 times more sensitive but it feels good in a way idk what's going on. Anyone have a suggestion on what this is?
