I'm 10+2 today and went for my flu jab this morning. All fine, didn't hurt and carried on as normal. Fast forward 6 hours and I feel awful, beyond the usual morning sickness and pregnancy symptoms I'm used to. I haven't got a fever but I'm exhausted, achey and just feeling really under the weather. Has anyone else experienced this as a reaction to the vaccine, or am I just coming down with something else?
