Reseed w irregular periods

Lonnice • 25 TTC baby #1 👶🏾

So has anyone with irregular periods used preseed? I want to give it a try but I know you’re supposed to use it during your fertile window..which of course without a regular period is hard to track.

I do plan on buying some ovulation tests just to see if I will get randomly lucky, but it’s not likely soooo was just wondering if I should still use it. Or if anyone else has?
