I once had two sacs but just one heartbeat. I was told to come back in a week to see if the second baby had caught up. My twins are 12 now. You just never know. (I don't recall at what week I was at the time, it was early - I'd guess about 7-8 weeks.)

My suggestion to you is to stay positive and behave as though you are viably pregnant (healthy diet, no alcohol, etc). If you have, in fact, lost the baby - that simply will not change no matter how much you worry about it over the next 6 days. Conversely, that period of stress is not good for you or your baby, should all be well in the end. I'm sorry they seemingly focused on the negative and gave little hope...I think it's important you know the situation but it seems they could have been a little less direct and pessimistic. As evidenced especially in infertility treatment situations, in pregnancy, people sometime do beat the odds.
remember, with all advice or suggestions for your hair, YMMV!!
My hair:
2b wavy, medium texture, low porosity, med-high density. Protein finicky.
My routine:
Cleansing: DCNP, every 4-5 days (occasionally use CJ cleansers).
RO: CJSC, occasionally use JCDC
Gel: KCCC, CJCIAB for 2nd day hair (sometimes third)

Heat is my friend: warm water rinses, steam caps, and diffuse dry. I love CLU cloths and my Denman.
