6 weeks after D&C

Tarra

Back on May 17th I had a D&C; done. I had my check up with my doctor on May 31st. He said that I should be ovulating within a week or two and have a period at the end of June. My husband and I had unprotected sex within when he said I would be. I still have no period today (June 28). I took a pregnancy test yesterday and today and they have a faint positive line. Could this already be a new pregnancy?
