But do you think my period might come this month or next because yesterday I had a really bad headache and sometimes I get angry with someone for no reason.

Look, headaches and getting angry for no reason can indeed be signs that your period is coming. Like, the body is preparing and sometimes these symptoms appear a bit beforehand. But it's impossible to know exactly if it will be now or next month just from this, you know? That's because every body is different.

What do headaches and bad mood mean?

These symptoms are quite common and can be part of PMS (Pre-Menstrual Syndrome). PMS happens because of hormone changes in your body before your period. It's like a rollercoaster of emotions and physical sensations, and headaches and irritability are some of them. It's normal, don't worry!

What you can do

• Pay attention: Try to notice over the next few days and weeks if you feel anything else different, like mild cramps, sore breasts, or sometimes a different vaginal discharge. These are other signs that might indicate your period is near.
• Take care of yourself: If the headache is bothering you, talk to an adult to see if you can take something. And if the bad mood is intense, try doing something that makes you happy, like listening to your favorite music or watching a funny video.
