Desperate for a little help.

Polycystic ovaries.

Very irregular periods & ovulation.

No period for 5 months up until 1st September.

21 weeks & 5 days pregnant with a due date June 12.

My ovulation is so off that my app is calculating my period to 6th September.

Roughly can anyone tell me when i would have conceived/gotten pregnant as its an easier was to get my app to my actual EDD.

Driving myself crazy as i have no idea at all😩
