Hi guys! So my husband and I only started ttc in September and I thought to give OPK a try this cycle because lots of you were saying on other posts that glow just predicts and your actual ovulation date could be before or after that predicted date. Anyhoo, according to glow I was supposed to ovulate on Sunday and Flo and fertility friend said Friday. We did the BD on Friday but couldn’t over the weekend, nor could I check if I were ovulating or not. Today is cd 16 and I took the test.. does this mean I missed my ovulation window?
