I had a D&C on Sept. 4, just over 3 weeks ago, since then I've had intercourse 4 times. I only had bleeding after two times, which stopped within hours. Since the last intercourse, I've been spotting brown discharge and I was wondering if it was normal it's been going on for about 5-7 days now, and it aggravating. Also, is there a possibility that I could already be pregnant again?
