I took planb twice in 1 cycle four weeks ago and bled twice, since then ive had unprotected sex and I'm having hip pain, is my period just delayed?

Another one. You would need to take another Plan B if you had unprotected sex again after taking it. It seems like you need a better birth control plan that would help you avoid these scares. Plan B can cause some cycle disruption. Always check a pregnancy test after using Plan B Please see a doctor to discuss options and to have your hip pain evaluated.
