I am on my 6th day of period with spotting 1-2 times. i had unprotected sex for a minute but he pulled out. then we only had protected sex. i also had been on antibiotics for cold cough, so i want to avoid taking the pill. however should i take it?

If sex happened less than 72 hours ago and you do not want to be pregnant, it would be prudent to take plan B (emergency contraceptive). While the risk of pregnancy is low it is possible for you to get pregnant. Pecum has enough sperm to cause pregnancy. Pregnancy is know to have occurred from sex on any and all days of the period. Get HPV vaccine. Wish you good health!

If you have missed any scheduled dose of your birth control, then you open the possibility of getting pregnant whether you had unprotected sex for a minute or days. A minute of unprotected sex is also all it takes to contract an STD, even if you have been on schedule with your pills. There is no significant interaction between antibiotics and birth control but antibiotics don't work on colds.
