Possible miscarriage

Samantha
Hi everyone,
I woke up this morning with a dull low back ache (my usual period symptom) and have started light bleeding.  Sorry to be gross but it hasn't stained my underwear but see it on the toilet paper.  Im meant to be 10 weeks 3 days.  I had an US at 8 weeks and everything was fine and HR was 157.  I'm currently at the hospital waiting.  Has anyone experienced this and the baby is ok?  Please pray for us :-)
