yes
Your question is not entirely coherent. Although, I think you're asking how long semen can be detected in the vagina for an analysis. Semen can live up to 5 days in the vagina and still be analyzed.
no it takes at least 4 days for body to show if pregnant or not
there is a 56 percent chance that you are and a 44 percent that you arent. It might be that there is a problem in your vagina or your old.
if you have your period you are not pregnant
its always the 14 days after your period. ( to get pregnant)
can i get pregnant 2 days before my period starts
If you have period you are not pregnant.
You can get pregnant at anytime, whether you are on your period or not
If sperm or semen contacted your vagina then a sheer possibility occurs, if not, calm down...
No, you cannot get pregnant on your period...but you can get pregnant as a result of sex during your period. During menstruation there is no egg present to fertilise, however there may be fertile quality cervical mucus which can keep the sperm alive in the vagina for up to 7 days, by which time your period may have ended and you may ovulate.
You can get pregnant at any time but you are more likely to get pregnant 14 days after your period
If you get your period, you are not pregnant.
