Long story short, I'm not on birth control and after having sex with my boyfriend, we noticed the condom broke. I took Plan B 20 hours after the incident and had a "period" two days later. The period was normal flow/duration, but it was two weeks early. I haven't got my period since then and it's been almost three months. I get cramps every now and then but that's it. I took a pregnancy test a few weeks ago and it was negative, but I peed on the window a bit so I'm not sure if it foiled the test. The test was Clear Blue though, so I'm not sure if that makes a difference. Any thoughts? I'm panicking a bit.
