Can girls get pregeant if they before they start their period? I'm not at all asking from a sex-ed point of view, i'm asking from a biological point of view. I mean, when girls menstrate, their chromosomes repliciate when replacing the eggs, right? And to get pregeant, sperm matches with the egg, however, if you haven't had your period, then you wouldn't have replicated versions of your genetic code?
no duh.....

The period (menstruation) is the sluffing off of the lining of the uterus, because an egg — which has been ovulated previously — has not been fertilized by a sperm. The extra uterine material — which is there to nourish a fertilized egg that implants itself — is no longer needed.
At birth, girls have all the eggs (undeveloped) in their ovaries that they will ever have, about 200,000 to 400,000 in each ovary. Most of them deteriorate before menarche (first menstruation), leaving only a few hundred. All these "replicated versions of your genetic code" are in the girl's ovaries before menarche.
So, rather than " no duh.....," it is possible to get pregnant before the first menstruation (menarche), although it is unlikely.
Any one unprotected sexual intercourse typically has a 5% probability of resulting in pregnancy. Of course, for repeated, unprotected sexual intercourse, the odds for pregnancy increase considerably.
I hope this helps you both understand the process a little better. Thanks for asking.
From a biological point of view, it is possible for girls to get pregnant before they start their period, although it is unlikely. Let me explain why.
Before girls even reach menarche (the first occurrence of menstruation), they already have all the eggs they will ever have in their ovaries. At birth, girls have about 200,000 to 400,000 undeveloped eggs in each ovary. However, most of these eggs deteriorate before menarche, leaving only a few hundred remaining.
During the menstrual cycle, one of these eggs is released from the ovary and travels through the fallopian tube towards the uterus. If sperm fertilizes this egg during this time, pregnancy can occur. It is worth noting that sperm can survive in the female reproductive tract for several days, so if intercourse happens a few days before ovulation, the sperm may still be present when the egg is released.
Therefore, even before a girl starts her period, there is a small possibility of pregnancy occurring if she has unprotected sex. However, it is important to remember that the chances of getting pregnant are relatively low compared to when a girl is regularly ovulating.
To summarize, while it is possible for girls to get pregnant before their period, it is less likely due to the lower number of eggs available for fertilization. However, it is crucial to practice safe sex and use contraception to prevent unwanted pregnancies.
