on friday i went to the doc for my six week check up from loosing my baby, and talked to her about the faint line so she is checking my hormone so we will see what is going on it probably is hormone left from the baby i was pretty far along so it probably would take a while for it to go out of my system.
try another test with EPT or FRER
Hmmm after 2 weeks the line should be getting darker not stay really light. If I was you I would get a doctors appointment and get your levels tested to see if they are rising or falling... or if there is still some tissue left over from your miscarriage.
As for being more fertile after a miscarriage it really depends on your body. I got pregnant again 6 weeks after mine but I have heard of it taking people months to get pregnant again.
