Advice ladies?! Greatly appreciated

So I know I ovulated on my left side this month. I'm in the tww right now. I keep having on and off pains in my left hip area and pressure. Tuesday night it was pinching and burning, today is crampy and slight pains but on the left and center still. Boobs are very full and nips are a little sensitive (it's also 27 degrees here lol) anyone experience this before as implantation, or does implantation feel cramps in the center of the stomach?
