Is it possible that after the first meeting of male and female through sexual inter course the female become pregnant after the sex??​

Yes, it is possible because, if the sperm from the male goes into the egg of the female it can cause the female to get pregnant by that male. And its very rare for the female not to get pregnant after having inter course with the male. That's only if they had unprotected sex.

I hope this helps you!
