yes, you suppose to take the plan b pill within 72 hours of unprotected sex. you had sex on Tuesday and 72 hours expire by Friday. Even though u took the pill Friday night, that is at the very end of the time allowed for you to take the Plan B pill and for it to work effectively. So the answer is YES, you may still get pregnant.
Thanks soooo much for responding soo fast! But i thought it worked up to 120 hours? Do you thinkk my chances of pregnancy are low?
I don't know, but a very inexpensive birth control would be a copper IUD. I have one. It does increase blood loss for a few months at the time of the month, but other than that I have had no problems. A condom would still be needed to protect against STDs.
Im allergic to latex. And the other ones make me feel funny down there so i nix them altogether.
to answer your previous question, your chances of becoming pregnant is low but still possible. good luck!
