I'm nearly 21 weeks pregnant and for the last couple weeks I keep feeling like I'm going to faint all the time. It's happen more and more as the days go by. I could just be going about my day as normal then all of sudden my head goes I go hot my visions starts blurring and I just basically feel like I'm going to collapse any minute. I don't have to be on my feet for long periods of time or standing up too quickly for it to happen. Just wondered if anyone else experienced this. Tried talking to doctors/ midwife about it and they just said it was normal however that's not really helpful as it's not a nice thing to experience all the time especially as I have a 2 year old and don't want to actually faint if I'm on my own with him.
