Really, another inconvenient period? Please, tell me a time when it would be ideal fo your period to come. And don't say "a week after the condom breaks".

Nightmare! Spose the lesson there is when you have another exam wear a pad just in case.

Was the test for your Second Period Class?

slow learner?

You don’t know your clock by now?

I’m not gonna say you deserve it, but one of two things is happening here: either you’re not paying attention to your cycle timing or your period is very irregular. If it’s the former, tracking your period will seriously help you avoid this situation again. If it’s the latter, I hope you talk to a doc about it. Nobody should have to deal with that happening more than once!

Was it the same professor?

Another? This time? Maybe you should just wear pads to all your exams from now on if you don't know when to expect a visit from Aunt Flo.

I highly recommend the website MyMonthlyCycles, or getting a period tracker ap. My cycle forecast is nearly always correct. I start wearing liners 2 days early just in case. So sorry for the embarrassing situations. Get an ap. Then if you see you are always irregular you can talk to a dr.
