Need advice.

When I was 19 I had a miscarriage at 6 weeks. When I was 20 I had another miscarriage also at 6 weeks (both with my ex). I use this <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> to follow when im ovulating. Im just wondering if the app has worked for everybody else. Is it accurate?

I'm now 23 and me and my boyfriend have been trying for a few months. I thought last month was it but AF decided to be 6 days late and surprised me in the middle of the night.

My boyfriend thinks he cant have kids, but we've all heard that one before!

I just don't understand why my past pregnancies ended at 6 wks. The doctors have never told me anything.
