Someone please help!! Last period cycle, I took a Plan B pill, it worked. We used a condom but it ripped, so we took anPlan B again. I know doing that can cause your period to come earlier or later but now I'm 3 days late compared to last month when i started on time. We bought a pregnancy test, the kind that you can take 6 days ahead. I took one on the 1, and it was a negative. I haven't had any constipation or fatigue. Overall, nothing has really changed and I have 0 signs I could be pregnant. Someone please help or explain what's going on??
