Stress and swollen lymph nodes

Nelly
Two almost three weeks ago I had a swollen lymph node so huge you could see it protruding from my armpit told my Obgyn my concerns and she ordered and ultrasound for me they couldn't see me for two weeks ,two weeks is up and the lymph node went away so I ask my doctor if I should keep the appointment which was this Thursday she said no you should be ok .,..Thursday I woke up with a huge lymph node but in the right side ....then today a new one appears on the left side again and the feel horrible extremely painful and getting bigger  I'm wondering 🤔is this a pregnancy issue or something else😔
