Any testing tomorrow?

I got my positive opk two weeks ago today. No positive tests yet, but I'm going to test again in the morning! I've had sore/heavy boobs and cramps Saturday that lasted until yesterday morning that felt just like AF cramps, with one tiny bit of spotting. Now just having weird pulling feelings alternating between both ovaries, and my cervix is really high! Really hoping it was implantation bleeding yesterday and that I'll get a faint positive tomorrow!! Anyone else? Been trying since December...
