Hi mommies I’m new here.

I’ve been nauseous/throwing up for over a week. I’ve had some positive tests & some negative tests. Super dizzy & tired. We’ve been ttc for baby #2 for a while now & I’m trying so hard not to get my hopes up. My last period was September 3rd, I supposedly ovulated on the 22nd. Yesterday I started bleeding it’s been pretty light reddish pink.this was yesterdays, not filling a pad but today’s is a little darker at first but continues to get lighter. Still have all my symptoms & I pee every 5 minutes. Is this implantation bleeding or AF? Normally have VERY heavy periods.
