Cycle day 47!!

Hi ladies!! Okay so my last period I got was two weeks early then what I normally get (usually on a 35-45 day cycle) so I was concerned but my doctor said it was fine even though it was odd for my body (in my opinion) so now it's been 47 days since my last period started!!! 
I took ahpt test and it was negative, I have slight cramping and my boobs are slightly sore, I have some stress going on but this is stressing me out more!! Any ideas or advise ladies!?
