Hi I am about seven weeks pregnant. Last weekend I had a little brown discharge, they put me on bed rest. Then I had an u/s and they now think its no longer viable b/c my hcg levels dropped. The u/s showed a sac and maybe the fetal pole but no heartbeat. U/S at 6weeks. Should I be worrying about this? They say they want to do a DNC. I am uncertain if I should let them until we are 100% sure this pregnancy isn't viable. Any advice other than to continue my prayers?
