So I went out to the shops tonight and was there for no longer then 20 minutes and was feeling perfectly fine until out of nowhere I started to feel very hot and started breaking out in a sweat and then my ears started ringing and my vision went funny (could see black and white squares), I started feeling sick and like I was going to pass out. I had to hang onto the isles just to be able to walk to the self serve checkout where I had to put my head down and lean over to rest the weight of my body so I wouldn't fall over. I stayed like that for about 15 minutes until I started to regain my vision and could pay for my bottle of water and make it to a chair to sit down.
My question is does this sound like anything serious or just a random pregnancy spell? I am 28 weeks and being light headed is not new to me during this pregnancy but this was something else, I was really scared of passing out in the middle of the store. My next doctors appointment isn't until the end of next week so not sure if I should just wait until then to get it checked out or try and get seen sooner. My vision and hearing have gone back to normal now but I am still feeling light headed, almost like my head is floating and feel very tired despite having a nap today and just kind of out of it for lack of better words.
Has anyone else had anything similar to this?
