I'm just wondering how long you TTC without success before going to doctor? It is only early days, I'm 32 this year and are going into 3rd month of actively trying. I'm just not sure that my body ovulated properly, I don't think I did at all last month judging by CM. I haven't used OPK's yet but will start this month.
Re: not being sure if you ovulate. The best way to tell if you ovulate is to take your temp - preferablly via vagina - the minute you wake up before you get out of bed and/or move about. Record the temps. Your BBT rises to indicate ovulation, and then drops again if you ovulate but haven't conceived. I had ovulation issues and to conceive DS3 consulted a naturopath/acupuncturist who gave me traditional chinese medicine to help me ovulate. She had me keep track of my cycle via BBT. It certainly was an accurate way of telling, and is how I knew I'd conceived, as my BBT stayed higher than usual. Good luck.
