Hi, today I'm 6 weeks and 1 day and all of the sudden today I've starting feeling a weird pulsating pain on my left bottom side of my abdomen. It happens when I do a certain move, or if I lie down on my left side. Has anyone experienced that? Should I be concerned? Sometimes it is like a less than a second sharp pulsating pain, but just on my left side... I'm so worried.. Considering going to go the ER for an ultrasound cuz I don't get to see my Dr for our first visit until Sep 13th.
