Can someone help me understand how the calendar works here on Glow? Pink period days are easy to figure out, but I notice all the blue days have a pregnancy percentage on them... I thought you could only conceive on green fertile days? Confused! Also, if you can conceive on regular blue days, would I have a chance at conception if my husband and I had sex yesterday and my fertile window begins in 2 days? Thanks for any and all input and sorry if I sound like a newbie, because I am lol
