The first human beings, known as Homo sapiens, appeared around 300,000 years ago in Africa during the Middle Pleistocene period. This period of time is known as the Late Stone Age or Paleolithic era.
No, it is not possible to have a late period one week after conception. Conception occurs when the egg is fertilized by sperm, and it takes about 6-12 days for the fertilized egg to implant in the uterus and start producing hCG hormone, which is what is detected in pregnancy tests. A late period typically occurs around two weeks after a missed period.
Pregnancy occurs when a sperm fertilizes an egg within 12-24 hours of ovulation. Ovulation typically occurs about 14 days before the start of a woman's next menstrual period. Therefore, a woman can become pregnant if she has intercourse around the time of ovulation.
During the Ordovician period, the first land plants evolved, as well as the first jawless fish, jawed fish, and arthropods like trilobites. This period also saw the emergence of the first coral reefs.
The three main types of sexual intercourse are vaginal intercourse, anal intercourse, and oral intercourse. Each type involves different ways of engaging sexually with a partner and carries different levels of risk for sexually transmitted infections.
That is entirely up to you.
If you have only just started your period in the last few months being late isn't unusual. But if you have recently had sexual intercourse there is the possibility of pregnancy. If neither of these is the case, maybe you should consult you GP.
Exercising can be a cause for your period to be late if you exercise daily.
It depends on what you mean by "safe intercourse." In using any method of birth control there is always a potential of getting pregnant. Nothing is 100% effective except for not having sex. So, yes, there is a possibility that you may be pregnant.
Its best to perform a pregnancy test, 3-4 weeks after you last had intercourse or when your period is a few days late.

You can, but you are not going to get a correct answer if you want to know if that one act of intercourse 5 days ago got you pregnant! I suggest waiting to see if your period is late, and testing then if needed. ~pawsalmighty
Most women miss there first months period after becoming pregnant. Some have their period throughout pregnancy.
Weight gain is irrelevant during the first trimester. If you had intercourse and missed a period pregnancy is possible.
yes. You don't get your period when your pregnant. when you first get pregnant though, some women have very light and short periods but that's it.
