Question about clomid

Sophia

I have been ttc for 14 months. I have my yearly appointment on the 14th with my ob. I want to see what my options are for assistance in getting pregnant. I want to ask her about trying clomid. However I use opks every month and get positives. I know a positive opk doesn't necessarily mean you will ovulate they just predict an lh surge. My question is have any of you tried it and how affordable is it
