Am I ovulating?

Lydia
I quit BC (Sprintec) on Feb 17, and I did not get my period back until Apr 11 and it ended the 17. I am all excited because now my husband and I can try for baby number two. Glow said today is my most fertile day. My question is, am I for sure ovulating? I have had light pink spotting the past three days, and my CM is like clear egg white consistency. Also , lots of cramping, a weird little pimple on my chin, swollen breasts, increased appetite. What's going on with me? Am I already preggo?
