question: Last week I had sex with my boyfriend and the condom broke so I took plan b within the 72 hours of having sex. Its been about 5-6 days now and I have felt any symptoms whatsoever. However, earlier today I started feeling urges to use the bathroom excessively when my body didnt really have urine to release. Then after a couple of times I noticed that instead of urine it was blood every time I used the bathroom. Could this be an effect of using Plan B? or could this be a UTI?
