Just uploaded <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow App</a> to see how it works. My husband and I have already been through 2 miscarriages within a 9-10 months span at 11-12 weeks each time and having to have dnc both times,  hoping with husband  off his meds and with new tracking app we are trying again. We have already had blood tests done showing nothing conflicts, spoke with fertility counselor, and this last pregnancy we had a faint heartbeat than next week nothing. Doctors/specialists  can't explain why we had the same trisomy miscarriage 2 times in row with exact thing. 2nd pregnancy we even used ovulation kit to track high fertile time and last couple of months we had sex several times in week during our most fertile time but still negative pregnancy test.
