Did anyone who didn’t track ovulation but dtd every other day not fall pregnant but then fell pregnant as soon as you started tracking?

Were onto our fourth month TTC which isn’t long at all in comparison to some people I know!

We’ve not been tracking and I have irregular periods so we just dtd roughly every other day which would think we’ve covered all days but obviously no success.

Is it worth <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> or not? And is there anything I can do to help?
