New AF symptom?!?!

Hey ladies, I am in need of a little advice! I'm 11 DPO, AF is due 3/8(stay away! 😫) and today I am experiencing a dull pain on my left lower side, about 3 1/2 inches from my hip. It's a pulling kind of feeling. Not sure if this is just AF and some new weird symptom, or something else. My husband and I have been TTC actively since November and nothing has happened yet. I don't want to test yet because it will just get my hopes up, so I am trying to tell myself it's just AF playing tricks on my poor nerves! Anyone else experiencing something like this?
