Dino asked
Will my next period in December be red or will it still be brown
Soso answered
It could easily be red, brown, or a bit of both, because there is no way to predict the exact colour beforehand.
Brown blood is simply blood that took a bit longer to leave your body. The iron inside blood reacts with oxygen in the air, and that reaction turns it a darker, brownish colour. That is why flow is often brown right at the beginning or at the very end of your period, when the bleeding is moving slowly. When the flow gets faster in the middle of a period, the blood comes out quickly, so it stays bright or dark red.
A first period can be very light or brown, and early cycles switch things up all the time. Your next period might start brown, turn red for a couple of days when it is heaviest, and then fade back to brown before stopping. It might also stay totally light and brownish the whole time, and that is completely fine too.
Most people bleed for 3 to 7 days, and a first period can be much shorter and lighter. Tell a grown-up if you need a new pad or tampon every 1 to 2 hours, your period lasts more than 7 days, you pass clots bigger than about 2.5 cm, blood leaks through to your clothes or bed, you miss normal things because of your period, or you feel tired or out of breath a lot.
If you want an easy place to write down what colour you see and when it starts, you can log flow and colours in the Soso app to see your own cycle patterns over time.
