Irregular period after birth control, TTC

I stopped taking birth control before my period back in December. It used to be every 28 days on the dot for the last 5 years. My period has been irregular since, which I anticipated. This is the first month TTC. I felt some ovulation symptoms near the 28-31st of March so that seemed to be fairy accurate. Has anyone experienced something like this and were able to conceive fairly soon? Or did your period need to become regular again and then it happened? Planning to take a test on Thursday which would be 10 DPO. Thanks!
