Ovulation question!

I’ve been off the pill since early November. I had my first period in December (I think it was 39 days after I stopped the pill), and again in January (29 days after the Dec period)

December, I ovulated at some point before my period (couldn’t track the cycle day since I didn’t have a period before that).

January, I ovulated on CD 19.

Now, I’m at CD 19 and NO OVULATION yet! I’m freaking out just a tad here. Is this normal? Do you ladies ovulate on the same day monthly? Give or take how much?

This is supposed to be our first “go” at trying for baby #1, so we’re just impatiently waiting for that positive OPK strip! Thanks for your input. ❤️
