First trimester - is anyone else not really into sex right now?

I'm 9 weeks and for the past month or so (basically since I found out!) I haven't had nearly as much desire for sex as I normally do. A few times I've WANTED it, but most of the time it's kind of felt like a chore. At first it caused some spotting (and therefore stress!), and was painful, so I wasn't worried that I didn't want it then - it made sense to me, with those issues. Now those issues aren't really a problem anymore, but I'm just so tired every time he tries that I'd rather go to/stay asleep 🙈 I used to have a pretty high sex drive, so this is really weird for me. Anyone else experiencing this?
