I am also ttc, have been for about 10 months. I was on Clomid for a couple of months and used OPK's which came back positive while on the Clomid. Have you been to the dr yet? I know that if you go to the dr they can monitor you to see id you ovulate. I know it's difficult to determine that if you don't have regular cycles but maybe they can prescribe you something to regulate it, and then something to help you ovulate if you don't ovulate by yourself. I haven't had any luck conceiving yet, am going to the gyn/ob again tomorrow as there's something else wrong with me. My period is VERY light and lasts only a day. I'm hoping it's not serious.

Good luck to you, I hope this helps a bit.
