Unlikely but not impossible
Oral consumption of sperm will not lead to pregnancy because the sperm will never reach the egg.
No. If you are one week pregnant, technically you will not have missed your period yet. Pregnancy is counted from the first day of your last period. So during week one, you are on your period. The pregnancy will usually be detectable around week 3. That is when the egg meets the sperm and implantation occurs. Once the ovum (egg/sperm) has implanted, your body will start creating the hormone HCG (that's what the pregnancy tests are looking for).
no, after a while the sperm will die (kinda creepy, right?) and they will come out during the next period. otherwise girls would get pregnant right after a pregnancy over and over again. no bueno.
What do you mean exactly? If you mean you finish your period and then got sperm inside you and your period came back it means your pregnancy was a failure
Highly unlikely. No, typically the egg accepts only one sperm. Any sperm during or after the event will have no affect on the pregnancy. No
It initializes the pregnancy by supplying one half the needed DNA.
Yes it is safe.
Yes it can, you can get pregnant during your period
No, sperm are required for pregnancy.
No, once the egg is fertilized with a sperm and his DNA it can not be changed. The uterus closed and nothing can in in if you are referring to sex during pregnancy.
Yes you can get pregnant while on your period -
Can, if man's sperm will get on genitals of the girl
