feeling upset need help!

So ever since I got pregnant.. I haven't been wanting to have sex with my SO.. and he's like been really horny so yea I feel like I have to pleasure him because that is my love but it's been a couple of times where I just don't feel any thing ( You know... down there 🌸) whenever we are doing it so I sometimes pretend to enjoy it and sometimes it gets to the point where it just hurts like I'm not wet enough to feel good 😔 it's to the point where I feel worthless because I can't get horny or wet enough to feel good. I mean, my hubby and I use to do it like every other day and wow it was good but now baby #2 is on the way and i just don't have the urge to have sex. Is there maybe something wrong with me or my lady parts ..?? need some advice 🙏
