I had the flu jab several weeks back now, no problems at all. I have my whooping cough jab on Monday, all I've heard from friends who've had it is that it gave them a dead arm!
Try not to worry, there's a lot of scare tactics atm from anti-vaccine supporters. I've had to step away from the PC more than once on another site, in sheer frustration at the bullying, viscous and almost cult-like comments being pushed around about having any kind of medical attention whatsoever, including these jabs!
Just remember that the NHS, and health organisations in general, would not pass something as OK for use during pregnancy if it wasn't. As always, with any reduced movement, contact your midwife asap - but there is no factual, scientific evidence to back up the idea that a flu jab or whooping cough jab has that effect!
