Opk help

Natalie

Ok so bear with me, I’m on cycle day 15 and glow predicted that I would ovulate today. Yesterday and today I took opks and both were negative, barely a line to be seen. Last month I took one 3 days after glow predicted ovulation and got a pretty strong line. I input the opk into glow today and it changed my predicted ovulation date to two days from now.

Would you wait for a day or 2 before testing again ?

How many of you have a 29 day cycle and happen to ovulate ‘late’ as in on cycle day 17+ ?

Any advice/help is greatly appreciated
