Possible Infertility?

So, my husband (29) and I (27) have been ttc for four months now. I KNOW that’s not long, but my cycle is very irregular (it has been for most of my life) and as Ive tried to track it I’m increasingly scared that there is something wrong. I currently have a catastrophic insurance plan and am wondering if anyone has advice on the best affordable places or tests that I need to get done? I’m honestly just scared that my irregular cycles (67 days between the first two off bc, and 47 days between the next) mean I’m not ovulating and that something’s wrong. Does anyone else have any similar experiences or advice?
