Glows Peak Day vs OPK peak day
Okay so I took clear blue easy digital OPK from the 16th to the 23rd. Always first thing in the morning. The test only had the 20th as my peak day. Glow had my peak day as the 25th. I'm scheduled to start AF on 11/8. We had sec every night from the 17 to the 21st. Which ovulation peak day should I follow? Also my cycles range from 27 days to 41 days... any helpful advice?
