im worried

I'm 4 weeks and 1 day pregnant as of today and I went to the hospital last night that's when they told me I was pregnant, but they couldn't see my baby well the sac... they said it's either too early or I could be having another ectopic pregnancy...I had a miscarriage in 2010 and a ectopic pregnancy in July...should I be worried?!

Did you get a paper with your HCG count? That could determine if they would have seen the baby at all.

So there is a possibilitiy that baby is so early that it is to little to show up on the ultra sound yet it usually takes until 1,000-1500 for baby to show up on the scan. So the next time you go to the doctor the baby should show on the ultra sound scan.
