Question: My questions is regarding the baby im carrying. My last time i had my period was on may 22nd.

I had an obgyn appt on XXXXXXX 3rd and she told me that i am about to ovulate within the coming day or two. I had unprotected intercourse on XXXXXXX 3,4,5 and maybe 6. I was trying to concieve and i acheived it that mont. now i am 21 weeks pregnant but i am so worried that the baby is from the one night stand. What are the chances that the baby could be his? Im so worried. Thanks

Brief Answer:
Not possible to conceive by that one night stand

Detailed Answer:
Hi dear, I have gone through your question and understand your concerns.
The one night stand you had was on day 7 of your menstrual cycle, which is generally considered safe for unprotected intercourse as conception is rare in t his period.
Moreover, you had protected intercourse with pull out method, which further decreases any chances of conception by that act.
Since your OBGYN told you that you were about to ovulate on June4 or 5, you are unlikely to conceive by that act. This is because the sperms remain alive only for maximum5 days in the female genital tract, and your one night stand was at least8 days before the ovulation. It is not at all possible to conceive by that sexual intercourse.
I suggest you not to worry.
Hope you found the answer helpful.
Please do get back for further queries.
Wishing you good health.

I had unprotected intercourse with my boyfriend on May 18, '13 (May 10 - start of my period) which is may last day of regular menstruation. No ejaculation happened inside me and my bf confirmed that. I'm getting paranoid cause I'm not yet ready to get pregnant so i researched some contraceptives and Nordette is the only available here in our country. So I took nordette 21(4 pills) and another 4 pills after 12 hrs, within 72 hrs after our intercourse. After 4-5 days (May 24), I got a withdrawal bleeding which happened for 4 days. I haven't got my period yet (June 9 or 10, '13) and I'm two weeks delay now. I haven't take a PT yet. Is there a chance that I'm pregnant? How long does Nordette can delay a period? Please reply to my question 'coz it will really help me to stay calm and not to worry. Thank you.

Hi, I m on birth control and I had unprotected sex two days ago. I have missed one (two at the most) days, but remembered immediately and took it. The pill I am on allows you to do this and take your next pill as you normally would without having to use backup birth control. I am now having a brown discharge and would like to know what you think this means and if I should take the morning after pill. Thanks.
