Hormone imbalance!?

Ok so I had what I’m sure was a really short period on the 13 & 14 (usually lasts 5 days) and I’ve been feeling so off like I feel slightly nauseous on and off daily. I am having cravings I think 🤔 like for example I keep thinking about egg salad or tuna salad or chicken salad( which I’ve never had before) on snack bread with everything but the bagel seasoning (which I’ve also never had before) and I’ve had egg salad a couple times but it turns my stomach to even think about it but at the same time I WANT to eat this or mixing things like putting chips in my macaroni salad. I’ve also had a lot of lower back weakness and pain to the point where I have to keep a pillow under me when I’m sleeping at night to get some relief. I’ve taken a couple amazon cheapie pregnancy tests days ago now but all Stark white so I don’t think I’m pregnant I’m just curious if this sounds like a hormonal imbalance or if some levels are off somewhere like vitamins or something 🤷🏻‍♀️ anyone have any insight or have similar experiences!!? Thanks

Also forgot to add I’ve been really wet and for lack of better word “loose” feeling like when I have sex with my husband I barely even feel him in there which is NOT normal he hasn’t said anything to me and I haven’t really wanted to ask if it feels different to him not sure if that helps any 🤦🏻‍♀️🤷🏻‍♀️
