Swollen lymph nodes after tDap booster...

Has anyone experienced swollen lymph nodes in their armpit after the tDap? I received a booster because I already had the full one three years ago with my 1st pregnancy. I got it in my right arm three days ago and now I have sore (not awful just uncomfortable) and swollen (pea sized) bumps on my right arm pit which I'm assuming are my lymph nodes. I plan on calling my doc on Monday but thought I'd ask here if anyone else has experienced this as a side effect. Thanks.
