HELP!!!!

Kim
So I'm new to the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> and tracking everything. Since I've been using glow I've been paying closer attention to everything. Glow says I'm fertile this week. Yesterday I had the egg white consistency and tonight I had it too mind you we bd Saturday night. Tonight when I had the egg white consistency it had a little blood in it. What could this be. We had a miscarriage in May at 14 weeks and this is our second cycle ttc.
