Best to see your doctor to check if a reason can be determined for the irregular cycles. This, of course, can sometimes make becoming pregnant more difficult.
There are some ways, both medical or herbal, that may help regulate your cycle, then in turn you would want to know whether you are ovulating, which your doctor can also check.
