I'm going to be talking to my dr about it on weds when I go but I've gotten this twice and its freaking me out. I've gotten like that flashing vision or whatever they call it like in my periphihal (idk if I spelled that right lol) vision it's like flashing and I can't see idk it's weird to explain. I know when I had my dr they diagnosed me with preeclampsia the day before I had her and kept asking if I had headaches and flashing vision then I didn't. Now I do and with headaches. I'm only 6 weeks 4 days and just wondering if anyone else has experienced this and what it was and what was done
