Help!

Before AF made her arrival I️ could’ve sworn I️ was preggers! I️ think I’m crazy bc I️ still feel like I️ am.. I️ had sore boobs for the first time ever, even had these little bumps on them. Plus it’s very rare I️ have back aches and my back was bothering me so much before AF. I️ was unreasonably irritable a week before AF until she went away (normally emotional if anything, most times no behavioral changes) and had a visible increase of cm also. During my period I️ threw up about 3 times which is abnormal. Post period (2 days today) I️ have been peeing ever 1hr or so which is definitely abnormal for me and experiencing so much heart burn. I’ve taken pregnancy tests but they’ve all been negative. Is this all in my head? Any advice is greatly appreciated.
