Advice

So I had started cramping about two days aho. The first night my crapping sharp and stabbing on left side. I had cysts on the ovary before. But I spoted enough to see it enough on towel paper but nothing on my underwear at all. I put on a pad and still havn't havent fully started. But now I have brown blood but not enough to say I started my period. My cramps are still horrible. They don't feel like premenstrual cramps but like period cramps. I havent had this issue with my period since high school which was more than 20 years ago. All I am saying on how unusual for me. I dont know if I should call this a period or not
