it would be nice if you could make it to the dr, but i know how money goes. they could tell you for absolute sure.
they didnt do a d&c so you could still have some stuff in there. i had to have them with both my mc. if that stuff stays in you can get an infection. that happened to my SIL. she had to have surgery and get some medicine.
it would be worth going just to make sure. and if they were wrong, they could tell you if your still pregnant too. do you have any family that would understand the situation and be willing to help out with dr money?
