I need advice

I haven’t had my period in 3 months. Going 2 months is pretty normal for me ( my periods are VERY irregular). My last period was in July. My fiancé lives 4 hours away so the last time we really did anything was September. Which is in the middle of not having my period. I know 100% he didn’t finish in me (This is really embarrassing for me) because we only really do it enough to get the feeling of satisfaction 🤦‍♀️ and then the rest is oral and hand stuff. Starting a few days I go I’ve pretty much got 0 appetite. I don’t know what’s going on with me. All advice is appreciated.
