UPDATE! Two different predictions... FF and Glow.

Danielle • 22 yrs old☉ Mama to a rainbow baby due August 4th, 2018🌈 Expecting my 1st baby❤

Glow and Fertility Friend have different predictions on when I ovulated. which one would you trust? I had a small dip today and want to know if I still have a good chance of it ending with a BFP. took a test yesterday and it was negative. UPDATE IN COMMENTS!

any help is appreciated❤ trying for my rainbow and first time charting!
