Worried🚨

Ok mommies so yesterday I got a REALLY BAD cramp for about 20 minutes max right up under my belly button I tossed and turned but it just wouldn’t go away,I passed gas and I kinda felt fine but usually when my stomach is upset from gas it makes a lot of noises and this time it didn’t ? The only thing that has me so scared is for the last couple days I’ve thought I’ve felt the baby move and roll over on my lower left side but when I got a ultrasound down she went nowhere near the left side to find the baby is it possible the baby moves when I flat down or was that just not what I was feeling ?? I’m almost 14 weeks by the way please Help !!
