Lower stomach pain

Sarah

I am 20 weeks with twins. Last night I carried my sleeping 2 year old from the car in to a restaurant. My husband kept asking if I needed help and I said no. By time we got to our table I was wishing I let my husband carry him! We ate dinner and everything was fine. But as we walked back to the car I hurt. I sat at the front door and had my husband drive around a pick me up. Now after sleeping this spot on my lower left stomach hurts if I walk or twist. Should I call me OB’s after hours line. I’m just so paranoid now that I’m pregnant with twins!
