Ok we have been TTC for about 3 years now and I've been using Glow to track my period for about 6 months. Glow is normally either right on time with my period or a couple days early but this month I've had to edit my period 4 times now due to it not starting. Along with having sore breasts for a little over 2 weeks. Wondering what some opinions are about what I should do. Should I take a pregnancy test??
