Itchy arm day after tdap?

K

Has anyone else experienced this? I just got it done yesterday and I don’t remember having a reaction to it when I got it done a couple years ago, though I wasn’t pregnant then. I have a pink circle around the injection site and I feel a lump underneath it. The itching isn’t unbearable and it’s just a little sore, so I don’t believe that I need to be seen or anything.
