Hello,

having sex up to 5-6 days before ovulation makes pregnancy possible. If ovulation has indeed occurred then - provided that the sperm was still alive and fertile - the plan B wasn't effective and pregnancy is possible. You can only get clues about pregnancy 10-14 days by measuring the blood levels of beta chorionic gonadotropin.

Kind Regards!

Does ovulation only happen in one day? And can i take a prego test now
doctor
Answered by Dr. Panagiotis Zografakis (43 minutes later)
Brief Answer:
ovulation happens 14 days before the period

Detailed Answer:
Ovulation occurs only once in every cycle. It's 14 days before the next period. That's why we can't predict the date. We can only estimate it, based on previous cycle duration.

Most pregnancy tests are useful right after the next missed period. A blood tests for beta chorionic gonadotropin is a more sensitive way to find out, although not conclusive.

Precentage waise what percentage do you think i am pregnant. Its eating me up alive i need to know
doctor
Answered by Dr. Panagiotis Zografakis (3 minutes later)
Brief Answer:
can't predict...

Detailed Answer:
Nobody can give you a percentage... Sorry about that. It depends on too many factors. I just pointed out that pregnancy is possible, judging only by the timing of the sexual contact. If any of you is not fertile for example then no pregnancy could ever happen. Besides that, even if you're both perfectly fertile, various factors may preclude pregnancy. Many couples try to achieve conception for a long time before actually achieving it.

If you're too anxious about it, then try the beta chorionic gonadotropin test.

Thank you! How effective do think plan b pills are?
doctor
Answered by Dr. Panagiotis Zografakis (2 minutes later)
Brief Answer:
they are very effective

Detailed Answer:
You're welcome!

Plan b pills are very effective particularly if taken right after the contact. The sooner the better. When taken within the first 24 hours they can be up to 95% effective. Please note that there's still a 5% failure rate, so you shouldn't rely on the pill.

doctor
Answered by Dr. Panagiotis Zografakis (3 minutes later)
Brief Answer:
no

Detailed Answer:
The answer is no. The pill only prevents ovulation from occurring. If ovulation occurs then everything goes on as normal.

How soon can i take a blood test
doctor
Answered by Dr. Panagiotis Zografakis (7 hours later)
Brief Answer:
10-14 days after ovulation

Detailed Answer:
The blood test can be taken 10-14 days after the estimated date of ovulation (which is very close to the date you can use the urine test). The blood test is quantitative though and will provide more clues to a potential pregnancy.

Kind Regards!
