Driving Me Crazy

Susan • Planning a wedding
Okay so it's no secret I have weird cycles. My doctor told me she found it weird, so she ran me through a ton of tests and nothing is wrong with me. My cycles are 57-60 days, but I have no idea when I ovulate, and you can see why when looking at my bbt chart. 
Basically what I've learned is that if I'm pregnant I could be pregnant for over a month without knowing it. Lately, over the past weekish ive been getting these really memorable dreams. I'm on medication for insomnia so I don't normally remember my dreams. Because of said dreams I've been sleeping really light and ending up super tired. Has anyone ever had this problem and been pregnant? Am I crazy? Does anyone have cycles like mine? I could use a friend on this.
