5 weeks pregnant/ bright red bleeding

I woke up in the middle of the night because my dog was freaking out and I got up to go to the bathroom and there was blood on my underwear and pajama pants. I put a pad on and fell asleep again for an hour. Woke up and there is still some light bleeding. I have no cramping and no clots in the blood. I'm aware this could mean a miscarriage but has anyone had this happen that didn't miscarry. I'm just trying to stay positive until my doctors office opens.
