App accuracy??

Kaitlin

So here the thing. I got my iud out July 17. I got my period on July 20th. Then exactly 28 days later I got my period again. It ended right at 5 days. I've never had a regular cycle like this. But maybe because I am 32 my body finally knows what to do. Anyway, the app says I am supposed to ovulate on the 30th. Would you all say it's relative accurate? If so, advice on how to get definitely prego? Lol
