Is this "normal"? (TMI)

Marie
We found out baby no longer had a heartbeat on December 12th. We were 11w3d. On the 13th I passed the sac. It's now the 30th and for the last 4-5 days I've had a brownish and creamy discharge. Tonight there is pressure on my lower abdomen. It feels nothing like cramps or anything that I've felt before but is very uncomfortable. I don't have a fever... Am I getting an infection? Or is all this discharge normal yet after this long? Do I need to go back in? Although I really don't know what they could do... Any input, info, advice please...
