Ovulation Spotting

Needing some help!! I have been TTC for 15 months. I've been trying to chart and track and it's SO hard! I have been having some very mild cramps and then a few sharp twinges on my right side. I checked CM yesterday and there was a VERY light pink/brown in it. My breasts have been very tender especially on the sides. I just don't know what's going on!
