late period, 2 BFNs and night sweats :(

Nia
My period is late by four days, I've done two tests which were both negative and I've woken up soaking with sweat for the last two nights. 
Usually this happens once during my cycle, around 24 hours before my period starts but still no sign of it this month. 
Now I'm worrying that it's early menopause (I'm 31) or something.
Going to Dr this morning to check things out but anyone else had similar? How did it work out? ?
