Im worried

J

I'm 26 weeks and Last night I had an awful pain on my stomach and I thought nothing of it because I thought they were Braxton Hicks but the don't last long but yesterday's pain did. I went to the restroom to throw up and than used the bathroom number 2 I'm sorry tmi. I thought ok maybe that's it but no the pain started at 10 and lasted for about an hour and a half my husband tried relaxing me by massaging my back but nothing than I had a strong pressure below my stomach. I don't know what it could I never went this with my first child and I'm worried because she moves a lot and since last night I haven't felt her move much and today neither what do you guys think it could be or I should do? I'm trying no to worry but idk what to do or think.
