Had quite a scary episode earlier today and wondered if others had experienced this?
I'm 26 weeks pregnant (first baby). I've always had low blood pressure pre pregnancy and it's never caused a problem as I knew about it and controlled it with frequent snacks/fluids (I've been checked for diabetes but don't have it).
During pregnancy it's been around 90/50 but again not caused a problem.
However, today I was teaching and stood giving an explanation to the group. Very suddenly I felt really faint, room spinning/going black so I had to rush out (thankfully a colleague was with me to take over). Someone helped me lie down on the floor, got me water and some chocolate. After about 5 minutes I started to feel better and remained sitting down. I feel ok now - not great but much better and I'm snacking lots. I'd had breakfast before work so had eaten.
Baby has been moving around so not concerned about that really.
Has anyone else had similar? It happened so suddenly it was really quite frightening 
Not sure whether to mention to my mw but don't see her now until the 5th Sept?
Thanks in advance x
