26w6d and falling

So I was at the park with dh and dd. I was holding dd and didn't notice a hole some kid had dug and I fell. Out of instinct I turned so dd wouldn't get hurt and I landed on my butt really hard. I couldn't breathe for a second. I feel crampy now. I can feel him moving around which is good. It just makes me nervous because that's exactly how my mom went into early labor with me. I was a month early. Dh is freaking out. I told him I'd just monitor how I feel like if I start getting contractions bad. He wants me to call. Should I be concerned?
