Confusing cycles and ttc!

For a year and a half now my husband and I have been ttc. There has been no luck and the sucky thing is, for a while my cycle would skip out on me for months. I'm not on the pill because I try to stick to natural remedies. I was suppose to start my period on the 14th, and it still hasn't come. I find it hard to keep track of my cycle with its inconsistency. And I don't want to get excited about a possible pregnancy and then be heartbroken again. Although my husband and I did have sex the two days I was at my peak. Are there natural ways to help with my cycle being irregular?
