Stabbing pains

Saturday I woke up at 2am with excruciating pain inmystomach I went to the er they checked my gallbladder, kidneys etc they said it's nothing and sent me home. I took milk of magnesium because I couldn't poop so I thought itwas constipation the whole night I was crying in pain. I had a trip to go to with my son and husband to fl he woke me up at 2am to get ready and as soon as I got up the pain started worse in my abdominal I'm 9 weeks pregnant btw. I went to the er at 2am again and told them the pain is still there it won't go away. They made me wait 5 hours didn't hook me up to no machine for fluids no medicine nothing. As soon as someone came they said they'll do an ultrasound. Got the ultrasound everything was normal doesn't sound like a miscarriage either. They told me to go home. All night I've been in pain the pain gets tense and I can only sleep on my left side. Has any one been thru this :(
