Has anyone ever experienced this before there period? I'm going to start my period in 5 days and I'm suspecting that I have a swollen lymph node on the right side of my pelvis .. It doesn't really hurt but now and then I do feel cramping, I barley noticed it today in the shower.. And I don't feel sick.. Just a little more tired than usual.. And I've been staying hydrated.. Should I call my doctor? I've never experienced this before.. Thank you.
