every woman is different but most symtoms start about 4 to 6 weeks after conceiving. as far a being fertile your body temp will go up a few degrees while ovulating. hope this helps.
at what point do the early symptoms of pregnancy begin? . is the earliest sign of pregnancy a missed period or are there observable symptoms of fertilization and/or implantation that can occur before a period is missed? how early in a pregnancy can the usual symptoms start? . . . . thank you <positive_smiley>
