So, I know for sure that I am pregnant, but I'm wondering which day I ovulated, so I can pinpoint my due date
. I was using
the Clear Blue digital OPK, and it says it's supposed to be positive two days in a row. Well, I started using the test on August 2nd, which was cycle day 10 for me. I didn't get a positive until August 12th, cycle day 20. (I'm breastfeeding my 14 month old so I ovulated late.) So, I only got the one positive on CD 20, and the next day it was negative.
