I have a question. Many doctor said that if we had unprotected sex and ejaculated sperm inside vagina then the woman can get pregnant and said if you had sex in january then her periods missed in february. Is it 100 % sure that her periods must missed the next month after sex? Or periods should missed in march or april? What is correct?
