I’m so damn confused. Can I throw this body out and replace it with a new one?

This is my current situation.

For the last two weeks I’ve been light headed, fatigued, nauseated, stomach cramps, going back and forth from constipated to diarrhoea, super super super sore boobs, had one bloody stool, lack of appetite and when ever I did eat, I keep on getting a metal taste and I also got tonsillitis over the weekend! CM mucus has also been clear and egg white for the last fortnight, but my ovulation kit says I’m not ovulating

Went to the doctors as all my pregnancy tests were negative and he was like ah well if those tests are negative then you’re not pregnant.

This morning, I finally got my period after being 12 days late - I think.

I’m saying “I think” because I generally get very heavy periods with horrible cramps. What I had was practically a two minute period. Wiped in the morning and there was a bit of blood like the tiniest bit. An hour later, there was just a light pink smudge. Half an hour later, nothing. No blood at all. No blood since either

Would you say that that blood was my period and my cycle now restarts? The only thing I can think of it being is implantation BUT the numbers don’t add up from when I last baby danced, when I ovulated and so on so forth
