Kellie - I dont get any real signs like ewcm or o pains or anything, so I still use the chart and OPKS. I then get a cd21 BT to see if I have O'd. With OPK's you can use them from 3 days after your last clomid pill... So i take clomid cd5-9 and start opks on cd12.
Some girls have u/s to confirm O too... what did your fs suggest? And are you bding every 2nd day?
