His and Her Health

Ok, I have a question, I finished my period on the 28th of October. Before I had that period, I knew I ovulated on the left side because of the pain. I normally dont ovulate on the right side because I get alot of cysts over there. Actually I dont ever remember ovulating on the right to where I felt it anyway. So yesterday the 11/5, I was running on the treadmil, and had some bad cramping on the right side just like I do when I ovulate on the left, and it happened on and off all throughout the day and it hurt really bad. NOW I am having another period?????? Is that normal? I have never had this happen before? I am 30 incase anyone needs that info, and have had kids. THANKS! for any help or ideas!!!
