I ovulated sometime between Sunday and Monday (I got a positive ovulation test on Sunday). All day sunday and Monday, I had cramping on my left side in the abdomen area. Today I have had twinges of pain (dull) in my abdomen, and my lower back mostly on the left side hurts. Is this a sign of fertilization or something?

It could be! I swore I was having signs of fertilization at 4 days past ovulation and well I am pregnant. So, you very well may be dear!!!!
