Being a First time Mom! Scary Stuff!

I Am 11 weeks Pregnant Today.. But on Monday I Had to go into the emergency room Because i started to bleed. I was Terrified.. Freaking out Even.. I Thought I Was Loosing My Peanut.. I never had any blood.. Not even implantation bleeding. So you can imagine My Concern. They Did Blood work and Ultrasound.. And Said it was A Threatened Miscarriage.. So then i almost died. The Nurse said the Baby Had A really strong Heart Beat Of 180.. So that Settled My mind a Bit. The next day I saw My Ob.. And He Said i Had a Low Lying placenta right next to my cervix So that's Why I was Bleeding.. I Bled A Couple More Times on different Days But Very Lightly .. And now It Seems to be fine.. I have an Ultrasound on Tuesday.. The 12th.. I'm Sure peanut is okay.. But Jeez I Can't Help But worry About every little ache and Pain.. And i know i'm Not the Only one! .. I wish i could have an ultrasound everyday To see my Munchkin!
