This has happened a few times to me. The first time in the shower. I start to get really dizzy, woozy feeling. Then my vision starts to turn black and I get extremely weak. I was able to sit myself down before I fell and finished my shower from the floor! Today it happened in a long line at the store, I was waiting about 10 minutes in line and I started getting woozy and weak and my vision started to black out. I made it to a chair and fanned myself for a few minutes and it took a while to go away. Is this normal? I've heard of the dizziness being common, but my vision really starts to turn black and I get light headed. Both times I have had plenty of fluids and protien in my system so its not that. I just had a check up and everything was fine with me and baby so Im just wondering what this could be? Im 16weeks and 3 days. Thanks for reading!
