My girlfriend has a problem of irregular period. period usually occurs on 9th of a month. On this December 9th she felt that she is not going to have period. According to her, period may come probably on 24th of December. On this 10th December we had an unprotected sex (4 times through out the night) and i didn t ejaculate the semen into the vagina (i am not 100% sure). In the morning (after 12 hours) she had taken unwanted 72. Today morning, on 15th of December she had a short time bleeding and also feeling nausea, vomiting, headache, abdominal pain, boobs tenderness. I highly need your advice and suggestions. I have listed my queries. Please reply me to get rid of this problem. QUESTION 1: Bleeding, nausea, vomiting, headache, abdominal pain..are these good signs not to get pregnant? QUESTION 2: When she may have her period? QUESTION 3: Is she pregnant? QUESTION 4: Does unwanted 72 totally destroys the ovum? QUESTION 5: Why this bleeding occurs? In our case, Is it flushing away the destroyed zygote or destroyed ovum? QUESTION 6: How long sperm can stay alive inside the vagina? QUESTION 7: Should she use a pregnancy tester? QUESTION 8: If she is pregnant, then what should we do? Is there any pill to avoid this pregnancy? PLEASE HELP..WAITING FOR YOUR POSITIVE ANSWERS.
