OVARY PAIN?

I am starting to think something is wrong. I have been tracking my cycles since Dec. 2013. My average cycle length is 32 days. Shortest cycle so far has been 31 days and the longest, 36 days. Idk when I ovulate. I have been having this WARMING/BURNING sensation in my/ where im guessing left ovary should be. I am going to make a doc appt soon but wanted some suggestions on what it MIGHT be. I am 4 days out/away from my period. Thanks ladies❤
