Period nose bleeds?

Angela
So this has happened to me 2 months in a row now. Last month the day I got my period (I usually get them during the night) and when I woke up in the morning, I had a nose bleed. Similarly, I got my period around 3am today and when I woke up at 10:30 I got a nose bleed. Does anybody get the same thing? Or know why? Or maybe it's just a coincidence?
