Am breast feeding for past 11 months, had unprotected sex two days after ovulation, am i pregnant?

Time will tell: well, do you feel pregnant? some women know right away. Most women in industrialized countries do not breastfeed enough to prevent ovulation after about 3 months. So, I would say, check a pregnancy test in 1-2 weeks. and "Act as if you are pregnant" meaning don't drink, don't smoke, etc. and if you don't want to be pregnant, start birth control.
