I used a Feetility Friend chart for the first time this month. I plugged in known data from last month to try and help give more data for the app to sync. Here's a picture of my current chart; my cervical mucus and positive OPK seem to correlate. My question- has anyone else had a positive OPK for only 1 day? What does this mean for when I ovulate? I had a darker blue line on the test strip the day before I tested positive on the OPK so I'm thinking maybe I actually ovulated yesterday? I had ovulation (I think) cramping last night and I've definitely had the fatigue but my boobs are normally SUPER sensitive/sore and I didn't feel that this time. Thanks for any info in advance!
