Late second period after Plan B?

I had protected sex on October 4th but the condom broke. To be safe I took Plan B within one hour of the incident. My period was supposed to start on the 13th but it didn't start until the 18th, making my cycle 33 days. A week after this period I took a pregnancy test just to be sure and it was negative. On November 7th we had sex again, this time protected with no complications. It's been 33 days since my last period and it's still not here. Took another pregnancy test on the 19th, 12 days after the protected sex. Is it too early to test? Or could my period just be late from the previous plan b cycle? My regular cycles are usually 29 days or so. I just recently started having sex. I'm in college with no plans of having kids any time soon, I'm really scared.

Hello Anonymous,

Welcome to EmpowHER and thank you for seeking our advice with your concern.

Some women experience changes in their menstrual cycle as a side effect of taking Plan B. Plan B works by preventing ovulation and can cause your next period to be delayed.

High levels of stress, such as associated with being a college student, can cause a late period.

If you do not get a period by November 24, test again. During pregnancy, the hormone hCG is produced. It can be detected in urine about 12 to 14 days following conception.

Thank you for responding Maryann. I took another test this morning, First Response, both came negative. Can I trust the results since it's been 13 days since the last time I had sex?
