I have never heard of that and
my doctor sure didn't tell me of such a pregnancy
. I took another bpt on Monday and
this time my hcg level was over 2000. I hope that this is a good thing. My hcg levels continue to increase. So, how can your sac continue to grow if there is no baby inside? If there is no baby then what happens to the sac? Were you having any symptoms, if so what were they or did you just show up for your ultrasound and that's when you found out?
