Sex drive is suddenly crazy?

My libido is suddenly insane and I feel honestly embarrassed about it.

My husband (m33) and I (f33) have been together for 13 years and we have an amazing relationship, but I suddenly cannot stop obsessing over him. It’s been a week and I’m literally begging him like 3 times a day at this point and can’t even concentrate on work lol I feel like we just started dating.

Has anyone else experienced this in their 30’s? I previously had a pretty normal to lower sex drive and I’m on Zoloft, so was is unexpected. The only thing I can think is that we had a miscarriage several months ago and are now back to TTC. Hormones I guess?
