TTC with irregular periods

Liv

If you're having irregular periods and TTC and can't seem to figure out when you're ovulating, do you just try to have sex every other day throughout your cycle? The last few months my periods have come on CD 32 the next, 48, then 23, then 30, etc. Just all over the shop. I don't BBT and can't seem to pinpoint when I ovulate. Thoughts anyone?
