Ovulating???

Carly • 3 little girls! Riverlynn 6/18/2013 & Rynnleigh 8/13/2017 & Rosalin 11/6/2018 and 1 little boy due 5/8/2021!

I'm so confused! Today I took a clear blue digital ovulation test and got just a smiley. I'd had been feeling some slight cramping so decided to take one not expecting it to say anything but then I get this?

According to glow my fertile window isn't supposed to be untill may 10th...is it possible I'm ovulating early?

Aslo my coles are about 34 day..
