Spotting

Marie
I recently just found out I am expecting with my first(I am 6 weeks today). I have been spotting since last Saturday a red/ brown mucous. I had an ultrasound and blood work done. My hcg levels keep going up, and the doctor said the baby looked good so far. Im just so nervous. I am bloated, nauseated at times and my boobs are sore so not sure what to expect. Help?!?!?
