The slight brown spotting turned into pink smears last night, and we confirmed by ultrasound this morning that I've had what's called a missed abortion. In otherwords the fetus died awhile ago, but my body did not trigger a miscarriage.
This will be my first, and with any luck last miscarriage. So I'm off to those forums to ask questions about what to ask my doctor.
Thank you to all of you here who have been so helpful. At least when we get pregnant again (hopefully) I will feel more prepared.
