I joined the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> 3 months ago as we have been ttc for 7 months now. After logging everything and seeing my ovulating and fertile days , I finally missed my period. I took 3 hpt 2nd day of missed period (last Wednesday)and 2 came out positive. I had 1 negative but was one i took in evening instead of morning. I immediately made doctor appt to confirm with blood test and it came back positive😍. My doctor was shocked i new already and said it looks like im only 2 to 3 weeks yet the app says im 4 weeks 6 days. I dont know which is correct. I felt the app was since knew my day to day but then again a blood test says alot. Anybody else going through the same or have any advice???
