Late period??

My period is late by like two months and I’ve always had a problem with irregular periods but never this long without one. I’ve taken two pregnancy tests and they’re negative so I was wondering if anyone had any secrets on how to jump start a period?? I feel like it’s not good for my body to not have one for two months. Been to my OB and she keeps saying “wait on it” just like when I had a 2 month LONG period she said “wait on it” so I feel like she’s no help :/ TIA
