Suggest Ways To Prevent Pregnancy
You cannot avoid pregnancy; you can terminate it
If you already had unprotected sexual intercourse for 15 days continuously, there is no method on the earth which can avoid pregnancy (you may have already conceived, so if you have have already conceived, how would you be able to prevent conception?). The post coital birth control medicines (Plan B pills) are to be consumed within 72 hours of the unprotected sex.
However, you can get rid of the pregnancy if at all your sexual relations have resulted in it.
So now you have following options to confirm the pregnancy:
1. Wait for the menses to appear on time. If they do not appear, perform pregnancy test on the overnight first morning urine sample about a week after the missed period; earlier, these tests may report false negative.
2. Alternatively, you may opt for Beta hCG test on the blood 10 days after the last unprotected intercourse. This is a very sensitive test. Pregnancy is diagnosed when the values are more than 25 mIU/ml while when there is no pregnancy, the values remain under 5 mIU/ml.
If either of the test detects the pregnancy, since it is unwanted, it can be terminated by medicines. Mifepristone and Misoprostol are the medicines which can terminate the pregnancy effectively up to 9 weeks of gestation. However, these medicines are not over the counter medicines. They should be taken by Gynaecologist's advice and are available only on prescription.
First get the status of pregnancy detected and then come back with the reports for further guidance.
