How quickly do you ovulate after stopping BC?

I stopped taking my Rigvidon pill about 4-5 weeks ago due to it making me really depressed and having mood swings. I’ve been on them about 9-12 months,

we have had unprotected sex since stopping.

My partner made a comment today that my boobs look bigger and they have been tender recently too.

I haven’t done any opk tests, we’re not trying to conceive but wouldn’t mind if we did.

I’m just wondering how quickly did you ovulate once stopping BC?

I haven’t had a withdrawal bleed yet.
