LH surge

Josetta
I need help/advice... i took an ovulation test for the past 4 days in a row and they all were positive, however how is this possible if it's said that you only get a day and a half (24-36hrs) until you ovulate after a positive test result? Also my fertility window (according to glow) was over 2 days ago! But today i got my 4th positive when i thought you only get about 2 peak days! Has anyone else gotten positive ovulation tests for SEVERAL days in a row? PLEASE DON'T JUST VIEW THIS, PLEASE COMMENT I NEED YOUR OPINIONS!
