Well, I'm not recommending this since it's just out of my frustration, but I am waiting this one out. Everytime I have gone to my OB/GYN with this problem in the past he has given me shots of hormones to "jump start" my system. Although it works for that month, it always seems to get me even more out of wack menstrually and emotionally. I found that when I let my body runs it's course I had more regular cycles. For instance this is the first month this year that I have been late (and I haven't given up on the possibility of being pg yet). Also, my Dr. told me that the next step is fertility drugs and my DH and I aren't ready to do that yet, so what would be my reason to go back. If I start hurting or having symptoms that I'm NOT used to then I will go back, but I still want to give my body a chance to work itself out. After all, I am young and healthy, I should be okay. Hope that helps.
