Did I ovulate?

This is what I have so far. Had two positive OPK's 5/18 and 5/19. Took one this morning and it is starting to fade. Last night I was getting cramps/ pains on the left side of my pelvis and my CM is raw eggwhite clear with medium flow. BD'd on the 18th when I got my first positive OPK. What do you guys think? This is my first time analyzing my own chart since its the first month TTC. Thanks!
