Hey Ladies!

So, yesterday after getting home from work I noticed that I had started spotting a bit, it was a light brown so I didn't worry too much about it. I also had some slight cramping in my lower back. This morning the spotting has stopped and I was very relieved, until I used the bathroom at work and noticed when I wiped quite a bit of dark brownish/reddish. It's not heavy enough to need a pad and I'm still only having very light cramping but I am absolutely freaking myself out.

Is this normal? I called the nurse hotline at my hospital and have still not gotten a phone call back from them. My appointment is still not for another 12 days, not sure I can wait that long!
