Feeling terrible

Stomach lowkey cramping, hungry, feeling weak, mini headache, and lil horny. 5 days or more away from my period because it never comes on thr same day 😒. I just feel like I want to vomit. I also feel a little light headed, I almost fell on the toilet 😂😂😂 I looked down to make sure my period didn't start and I almost fell forward. I think my cycle is coming because it feels like PMs symptoms. Some women would test before their period, but I'll wait for a missed period. It sucks PMs symptoms are the same as early pregnancy. I also used a Implantation calculator and it said I should implant today and I am cramping, but I'm not getting my hopes high.
