Help!!!! Please!

Im 5 weeks and 6 days today. I just went to the bathroom and noticed some brownish spotting on my underwear and when I wiped. I'm having some mild cramping, but I've had that the entire time and was told by my doctor that it was normal. I have my regular symptoms, but morning sickness was worse this morning. Is something wrong?? I tried to get ahold of my doctor, but it's after hours... my mind is jumping to worst case scenario. Please tell me it's not what I think it is??? Help.
