10 DPO, groin discomfort on left side overnight

Bria
So its our second month TTC and AF is due on Friday. Today my breasts started feeling sore and I woke up with a discomfort around my groin on left side. I didn't do anything to pull a muscle, so I wonder if it has anything to do with ovarian cysts (which I get on both sides each month). I've had cysts rupture before, but this is a new feeling. I'm taking a test tomorrow to see if I get a BFP, but my hopes are slowly fading away. How can I be so young and do everything right, yet still be struggling. I guess I'm going to have to settle with being a stepmom for a while longer. Stay away AF!
