I came off my birth control last month as me and my boyfriend have decided to TTC #1. I didnt use any OPK or taking temps last month we did DTD a lot but my period decided to show 27 days after stopping the pill on November 18th. I bought the advanced clearblue ovulation tests and Im patiently waiting to start using them. AF is almost over and Im on CD 7-8 right now. Im wondering when I should start the OPK tests? I definitely dont want to miss my ovulation. However off the pill my periods range from 28-45 days so I never know how long my cycle will be. Thank you for your help! Hoping this is the month!
