Implantation?

So we have been TTC for 2 years. I’ve been to the dr and she said she thinks I have PCOS, but she won’t do any test, etc. I have absolutely no symptoms of it. I ovulate when I’m supposed to (usually 2-3 days later than projected) but I still ovulate. This mont we tried the diva cup method on ovulation. At 9/10dpo I had the GOD awfulest pain in my pelvic/ovary area. Could that have been implantation? It only lasted about 2 days. I’m 11dpo now.
