Pregnancy ?'s: If there were contact of genital areas and semen was present even w/o ejaculation, pregnancy is "possible". If after 47 days of no menses, bleeding "17 days after last period" may represent pregnancy outside the uterus (ectopic). Obtain a serum HCG test, and see your gyn physician for an exam if positive, as a possible ectopic pregnancy needs immediate attention.
