Concerned!

Ashleigh • My partner and I are TTC, we are using an anonymous donor. We started trying in December! Can`t wait to be a mommy!
Hi Ladies, 
  This is my first time posting here. We just found out we were having twins...not just 1 baby!! 
  I was having some light bleeding on Friday so went in for an ultrasound. The Tech found our Baby B that day! I am 10 weeks now. The babies looked great, they were jumping around and their heart beats were both 171! 
  The bleeding slowed and disappeared, but it has come back today. It's a little darker than before. Did any of you other twin mommies experience this? I'm a first time Mommy so I'm terribly worried. I know we saw the babies and they were fine, but of course I'm still worried. 
  Any advice would be great! Thank you!
