Frustrated...

It's been a year and half of trying. I already have two kids, both we conceived around bc. I've been off a year and a half, and last time getting off my ultrasound showed I had an egg waiting. My theory is, I don't ovulate unless I have help. My frustrations are I worked so hard to regulate my cycle on my own without the bc and messing up again I really don't want to use it again. Anyone else have this issue and have used something to help ovulate without messing up an already irregular cycle? I don't have the thousands to spend although I wish I did, but just looking for some insight of what others have used to help in hopefully a similar situation, I'm so angry, sad, I never realized the issues before because I was on bc so long...
