High risk pregnancy: anomaly occuring?

Ok, im suppose 2 be about 6 weeks 4 days. I went wednesday for my first ultrasound, and the doctor couldn't definitively see ANY baby, but saw 4 fliud-like sacs. never said if they were like gestational sacs. But definitely saw no fetal pole or heartbeat or anything. They told me i was most likely having a molar pregnancy. got my HCG levels tested today, and they are 20,141.11, which is perfect for being at about 6 weeks. If it was molar they said it would be 100,000 or even higher, so molar pregnancy has been ruled out. Now they are telling me that either the baby is dead and that fluid is pools of blood, or im having between 2 and 4 babies at once, possibly more. Definitely got pregnant the old fashion way, lots of vigorous sex with no protection, and definitely no hormone treatments, and multiples do run in my family thru my mothers side, mainly twins but i believe a set or two of triplets have occurred. So, now i have to do another hormone check saturday but wont know the results till monday. Not only is the wait so ridiculously hard but i lost my last child at 34 weeks due to a knot in the cord, so im already high risk and nervous as hell!!!! Anyone else ever have ANYTHING like this?? as in multiple fluid sacs that had nothing in them and ended up being early twins or triplets or even quads??? I'm so nervous and just want some assurance from other mothers, or from anyone who knows about this. thanks in advance, and please keep all ignorant comments to yourself.
