I am 19 weeks pregnant with my second child. Today we went to the park and I was just walking and all the sudden I started seeing stars. My husband helped me get to a bench and I continued to see stars for a minute or so. This has never happened to me while pregnant. It happened to me once before I had kids while working out at a gym but went away as soon as I sat down. Has anyone had this happen? Is this common? I plan on calling the doctor tomorrow morning.
