Hi, I had protected sex with my boyfriend around day 30 (my cycles are usually 40 days long) but had an accident and the condom broke just as he pulled out. I immediately took plan b an hour later and have been experiencing symptoms such as sore breasts (at times, it's not overwhelming--like pms), head aches, fatigue, fever (lasting 5 days!)/intense sore throat/cold (related??) a week later. My period is late too (it's been 2 days but I know plan b messes with your cycle). I'm nervous... Are these plan b side effects? Am I pregnant?
