I had unprotected sex 3 nights ago and and took plan b pill last night then had unprotected sex again last night can i still get pregnant?

PlanB Effective120hr: No Plan B is effective for 120 hours that is 5 days .But my advise is that if you are going to keep having unprotected sex,use birth control pills or another method.Remember plan b is less effective as time passes and take it as soos as after sex for it to be more efeective.But plan B is effective only 89% if you take within 72 hours,And 95% if taken within 24 hours.
