Pregnant?

Hi girls! So I am now on day 39 of my cycle (my cycle ranges from 27-34 days but never more than 34. The average is 30). The last few days I thought I might have had my period but it was verrry light. Like not even enough to fill an 8th of a tampon. It was bright red-dark Brown. I took a test three days ago, it was negative, as well as yesterday morning. I have been having hot flashes, I’ve been very nauseous, and sleepy. I will probably wait a few days to see if I get my period but the suspense is killing me. Thoughts?
