Last cycle I tested for 11 days. All BFN.stopped for 2 then tested again and got positives. The night of day 4 my boobs were sore and had mild cramping. By day 5 I got the flashing smiley. And I was under the impression I ovulated on day 6. Then I got my period 2 weeks later.so glow says it was the 6th. Took a dollar store ovulation test this morning and I got this. I know its negative. But am curious if glow will be accurate this month too. How accurate is glow for you?
