Is it possible I ovulated on time?

So my periods have been very regular since I had my first baby. Occasionally it may come a couple days late. My March period was on time, however, my April period was a week late.

Hubs and I started trying this month, and based on what two separate apps say my next period isn’t due until the 12th and that I ovulated right in the middle of April’s cycle and may 12th.

But I’m already feeling dizzy and nauseous and I could sleep for days.

Long story short if my period was late, could ovulation have been on time? If April’s cycle had started on time literally the first official try was with in a day or two of when I would have ovulated. And also if had come on time my next projected period would have been Saturday.

I bought a test just in case but still curious to read what y’all think. TIA!!!
