I had my son by c section on March 15, 2008 and I still have not gotten my menstrual cycle. My huband and I had not had sex since I was pregnant, but we started to, two weeks ago. We did not use protection, but he did pull out. Should I be worried that I might be pregnant? How long does it normally take for someone to get their menstrual cycle after giving birth. I thought it was only about 6 weeks.
