Question about irregular periods when TTC

Hi!! So my periods have always been VERY irregular. I’m talking 50 days, 60 days, even 70 at one point. I went on birth control at 18 to keep things regular and then got off 10 years later. Got pregnant with our son 3 months off pill still waiting for my period to come back. It didnt but I guess I was ovulating.

Now we’re thinking about #2 but having a hard time figuring out timing. I had my period May 3 (first one since having baby 20 months ago). Tracked ovulation through test strips and was ovulating June 9. Did the baby dance. 😉😉 Would I know yet if I was pregnant based off my irregular cycles??

Looking for any help from any of you, especially those who have had irregular cycles as well!! Thanks in advance and hope that wasn’t too much info!! 😘😘
