<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctors! I had unprotected sex 4 days after my period at about 11:30pm. I took 4 white pills of Nordette Pfizer 8 hours after the deed and 4 white pills again after 12 hours. Then I took another 4 more pills in the next days and took again after 12 hours. So in all, i have taken 16 pill of nordette.is that ok? Will i get pregnant consume too much pills? What are the chances. Thanks.  <response>: Hi, Welcome to Chat Doctor forum. Actually the tablets Corvette should be taken in 2 doses, of 12 hours gap. If excess of the pills are taken, there may be no use, but they may interfere with the effect of the first 2 doses. When pills are taken out of the schedule, the effect may be indefinite, and may depend upon so many factors. Still the possibility if getting pregnant in your case are very less. The day of the sex is in the safe period. The first 10 days after the period are safe, because there wont be the release of the ovum to become pregnant. 11th to 20th day from the day of the period are unsafe, as during these days Ovum may be released on any day and ready for conception for 24 hours. 21st to 30th day again safe, because ovum is not available. If period is late by anxiety or something have a home pregnancy test. Wishing a good time. Thank you.
