2 day bleeding 2 weeks before AF

I had my period 11 days (18 counting from the start of my period) before I started bleeding/spotting for 2 days, my next period wasn’t due until a week and a 1/2 later at the time.

I baby danced the 31st of March and the 1st, 2nd and 3rd of April. I ovulated around the 1st-9th of April according to Flo but I bled for 2 days on the 3rd and 4th… I can’t tell if it was ovulation or implantation bleeding or just my period coming a week and a 1/2 early.

My period has usually lasted 3-4 days for the past year but I just came off my birth control about a month ago and my last period ended up lasting 7 days last month which is not normal for me but I’m guessing the birth control is the reason why.

I’m now 9dpo or so.

Here’s a pic of the bleeding and my calendar

Any ideas?
