Help! Anyone had the flu jab and allergic reaction with rash?!

Hi I just had the flu jab Yesterday as my midwife told me too and I have come up in an itchy rash first on scalp/neck now all over! Red spots all over and swollen lip and eye too! Anyone else experienced this in early pregnancy? (I am 6 weeks pregnant). Going to doctors this morning so hopefully they will help as the rash is extremely itchy! Just wondered if anyone else had this? I know our bodies change in pregnancy and immune system is lowered but never had allergic reaction before! Thanks in advance!
