Don't be too nervous yet, they'll figure this out for you!
I had a friend that bleed a lot at 20 weeks, had tons of tests run and all was okay. They never figured out the reason but her was born at 38 weeks and was perfect.
Valerie how SCARY Hopefully you are at L&D now and are OK!!!! Prayers to you and I"m sure its going to be fine, if anything they may put you on bedrest????
