Hi... and
I am sorry you lost your baby

I hope you heal quickly and are pregnant again when the time is right for you. I had a natural m/c at 14weeks but ended up with a D&C too. The D&C wasn't too bad. Hopefully you won't have to go that route.
About OPK's... I love the Answer brand...but not the mid-stream sold in a pack of 7. I like the dip kind sold in a pack of 20. That is the only brand (besides digital) that I get a clear positive with.
If you need help charting, just ask.... most of us here chart. There is also a Fertility Charting board here at justmommies
I can't wait to get to know you. We have a chat tonight at 8:00 in the TTC room. We would love for you to join us if you can.
Bobbie
