Ovulation Test Help

So, little back story. I finished my last pack of birth control in January (having a period on my “off” week February 3rd-8th.

Then I had another period or possible “withdrawal” bleeding from coming of the pill (spotting starting February 24th with normal flow 26th-1st).

I started taking the ovulation tests on the fifth day of my period since I don’t know the full length of my cycle being off birth control again etc. before birth control/after I started my period after breastfeeding for a year, I was super regular (I just never counted days) but I had a period every month etc.

So, this led me to wanting to know my actual ovulation day. But I’m confused since I figured it would be next week since I just had my last period February 26th-March 1st) but now these test are saying this week. Is that even possible to ovulate that soon!?

It was it just withdrawal bleeding I was experiencing!?
