Wacky period

August 24 - 28th : Last period before ⬇️ this

September 18th - metallic taste

September 19th - brown spotting (never had brown spotting before, always had pink)

Period usually come the 23rd / 24th but instead it came the 19th (start of brown spotting) it didn’t end until September 30th (eventually turned into red blood)

October 1st - nausea/vomiting all day

October 2nd - dizziness from 8am til evening (never happened before, even from me being “dehydrated”)

Is it possible to have implantation bleeding , and vaginal bleeding/period right after? That was a long “period” for me. And I’m clueless about it.
