Glow predicted af will arrive today. so far I only have mild cramps an dryness. Glow has been right for awhile. so I tested to see what is going on, but it was negative... so I checked other predictions now they all say I will start the 20th. anyone else get a positive with just those symptoms? I have an OB appointment tomorrow an they give a pregnancy test every visit. so if af doesn't show tonight or tomorrow. we will figure it out tomorrow (hopefully).
