Hi ladies! The past two days in a row I've had a very sharp pain shoot across my lower stomach, a pain I've not felt before. It was quite painful, enough to make me jump and shout "ow!", also a different kind of pain to what I usually get and it only lasted 3-4 seconds each time and only happened twice. Today I've had a strange sore niggle on my left side of my lower stomach. I am now 10dpo. However, no spotting... Could this still be implantation?
