That all sounds great! Let us know how the ultrasound goes tomorrow. Hopefully we'll see some definite progress. Don't wig out if the tech doesn't find a fetal pole yet. A sac with a yolk sac would be a very welcome sign of things progressing even without the embryo visible yet.

a stat some of the docs I work with quote is 1 in 4 successful pregnancies have spotting/bleeding to some degree. So yeah it's fairly common. It sure does freak people out though.
