Bright red bleeding

K

I have had very mild cramping on and off and tonight at work, I started bleeding bright red when I went to pee. Nothing was in my panties it just flowed right out. I'm really really sad. We tried a year and I had very positive tests. I'm 4 weeks, 2 days. Should I go to my doctor to draw serial hcgs? I don't think I could stand to wait one month before my ultrasound and not knowing.
