Are irregular periods really that normal?

Jessica

I’ve talked to my doc what feels like every year explaining to me my symptoms. I can go months without a period, get my period twice in one month, just spot for a day or two or have like a murder scene. And all I hear is it’s normal. I’m on the pill for pain and sexual reasons. But without the pill my back and stomach cramps are unbearable. Any advice? Is this normal?
