Today is Calendar day 17 and day 4 of blinking smiley face for high fertility. We have BD every other day since CD 6. Should we start BD-ing today like it was a peak OPK? I didn't use fmu and drink a ton of water throughout the day so I can't really retest today! I don't want to throw off the schedule if I'm not supposed to get peak until tomorrow but I don't want to wait until tomorrow if I was supposed to get peak today!
