Normally, women do not become pregnant immediately after their period takes place. Instead, it will take a couple of weeks before their body develops a new eggs, builds the uterine lining and releases the egg for fertilization.
However, every woman is different and it is possible for your cycle to be much shorter than normal. If this is the case, it is possible for a woman to become pregnant right after the period.
If a woman has intercourse immediately following her period and an egg is released within 72 hours, it is possible that it could become fertilized. One thing to keep in mind, though, is that if the egg does become fertilized, it is possible that it will not be able to attach to the uterine lining.
This is because the body sheds the uterine lining during the period and will thicken it throughout the month. If the lining is not thick enough for the embryo to attach, the embryo may pass instead of resulting in a pregnancy.
Most women will not be able to get pregnant immediately after their period. In order to determine when you are able to become pregnant, you should always make sure that you are tracking your ovulation cycle.
