Fell on ice today-need some reassurance!

I'm 15+2 and was actually walking into the hospital for my normal check up and fell straight forward on some ice. My knee hit and my hands first so I felt like I braced myself as much as I could. I was wearing a long padded coat and I don't feel sore anywhere like my hips/pelvis/tummy hit the ground hard but I'm still so worried. I of course told my OB and she palpated around my uterus a bit and I didn't feel any pain. She didn't seem concerned but now I'm at home and swear I feel different although I'm sure it's mostly in my head. I'm watching for bleeding just in case. I'm just so worried. First pregnancy. I've been told the baby sits so low still and is so cushioned it would take a serious blow to hurt it but still-I can't help but be worried sick! Thanks :)
