Glow ovulation calendar

B
Hi everyone! So I am a bit confused the month of march I had my period twice in one month last one ending April 2nd. Glow said my green fertile days were April 4-7. Now in my notifications it just let me know j am now ovulating starting today 4-6 and my most fertile day is April 10. On the calendar April 10 is blue with 3.0% chance of pregnancy!? What the heck!????
