I started my period on 9-12 and lasted until 9-16 (a day shorter than usual). It was heavy the first 2 days than very light. I stopped, i had nothing on the 17th. On the 18th I started spotting a dark brown blood color during sex and even when i wasnt having sex! I also have this odor that i have had and i cant get rid of it for nothing. I cant get into the doctor for 6 weeks. Can i be pregnant?
