This month I didn't track OPK or anything, just BD every other day in fertile window and it was very freeing!!! I still noticed my CM and logged that and BD, so I think the app was correct on my O day but it felt nice not to worry about it so much. Fingers crossed it worked this month! It's 10 months ttc #1 for us. I got a cute onesie to tell my husband, which says Daddy 2018 and this is the last month I can use it, lol. I'll have to throw it away if I don't get pregnant this month and make a new shirt that says 2019 because I'm hopeful it's gonna happen soon!!!!!
