HELP I FEEL LIKE ASS😭

D • God’s grace💗

So today ive just felt absolutely shocking. I feel extremely nauseous, I felt like I was gonna puke at one point but nothing came up and now just randomly my boobs have re-periodised them selves (I know it’s not a word) meaning they’ve re hardened and are really painful again. My period was due today I’ve not been getting any symptoms for the last few days except from faint cramps and back ache, and I’ve had pain in my vagina & a feeling like my period is coming but nothing comes. I’ve taken test and all have said negative. Does anyone know what’s happening to me? Right now I feel like a bucket of ass😩
