I had my baby on 2-20-2010 and had my tubes tied 2-22-2010. I had sex about a week and a half later unprotected with my husband and about 2-3 more time before I had my first period and I had sex after that also. I had my period 3-17-2010. It was light and lasted about 5 days when before I got pregnant it was sorta heavy lasting 7-8 days. I heard that after your tubes are tied you should wait 4 weeks before having sex. Is that b/c the tubes are not 100% closed and if so could I be pregnant or is missing a period normal after having a baby?
