Not sexually active ๐Ÿ˜ and husband has been really in the mood. What do I do?

Lupita โ€ข married an anime junkie like me. Love to watch 90`s sitcoms, and draw, paint, cosplay. my fav 50"s sitcom is i love lucy. my fav disney princess is jasmine. looking to make newfriends.
I haven't been sexually active for awhile. My husband has been in the mood alot lately and makes it obvious lol im not in the mood and been feeling really bloated and kinda nauseous lately. I spotted a couple days ago. Had some brown discharge for like 2 days I guess. Thought it was my period starting but my expected period wasn't supposed to start for another 11 days. I still have a little over a week to go till my next af though. Been feeling some soreness in my breasts. But been feeling kinda annoyed with my hubby every time he brings up sex. And we're usually very sexually active. But lately it's haven't been in the mood. How do I tell him in a nice way without hurting his feelings? I've been trying to tell him here and there I'm just not in the mood but it seems like he's not really acknowledging it. What do I do? Any suggestions? Plz no rude comments.
