We're on the same cycle. I am CD 14 today. I was told to start ovulation predictor on CD 13- CD 19. I'd keep testing up until CD 19.
With my doctor if I don't ovulate by Cd 16, they have me come in for a blood test to check follicles. I am still going to test for the 7 days, since I bought a kit for 7 days.
Oh forgot to mention I am also medroxyprogesterone to induce my period. After my last pill I started to spot 3 days later, but not a regular period until 5-6 days later.
My doctor told me when taking clomid the average woman will ovulate cd16, that seems to be when I do, so keep testing! I am cd16 now and got a positive on my OVK just a bit ago, also don't take the OVK's with first morning urine if you didn't allready know that, I didn't know last month and kept getting false postives till I found out you're not supposed to do it till the evening. weird.
