Hi everyone! I'm CD 23, 7 dpo. Last night I was woken up in the middle of the night with pain in my tailbone and the urge to urinate. I also had sharp cramping in my lower abdomen, below u belly button. I have no idea what it could have been, but I was thinking maybe implantation pain? It only lasted less than 10 minutes and I have no spotting. Anyone else experience something similar? Thanks!
