Implantation feeling?!

Okay ladies, this is my first post so im a little nervous lol. Please make me feel at home! I had a pinching pain yesterday on my right lower side. Could this be implantation? My bbt also dropped 1.6 degrees this morning so maybe its an indication? My bbt has been elevated until this morning staying between 98.7 and 98.5. Are these good numbers? This is our first time doing the bbt and cm, etc.
