Has Plan B messed my cycle

I had sex with my boyfriend on 30th January and the condom broke. I took Plan B a few hours later and my period arrived on time on February 9th. I then traveled internationally on 22nd Feb (Africa to Europe) and my period came early on 4th March. I traveled back to Africa on 8th March and had sex with my boyfriend and he pulled out. My normal period is due today, however, I am wondering whether I am late due to the fact the my March period was 5 days early? I've had no pregnancy symptoms i.e. spotting, nausea etc. I am just nervously waiting for my period to come. Can Plan B affect your cycle? This was the first time I have taken Plan B. When should i be worried and take a pregnancy test? I have also been under a lot of stress lately so i am wondering whether the international travel combined with stress is causing the slight delay since i am pretty regular. I plan to take a pregnancy test this weekend if my period doesn't show up.

Hello Anonymous,

Welcome to EmpowHER. I am glad you reached out to us with your concern.

Plan B can cause changes in the menstrual cycle. The next period could start earlier or later than expected. Flow might be lighter or heavier than normal.

Typically, this effect is on only the next menstrual cycle. In your case, you had a period in February and March.

From what you have shared, international travel and increased stress are more likely the reason your period for April is late.

If testing and seeing the result will give you peace of mind, then take an early response pregnancy test. For the most accurate result, test in the morning. Use the urine when you wake up and first use the bathroom.

Keep us updated,
