So the app says that I am finishing clearing out the top layer of my uterus what about other layers
Soso answered
The other layers stay right where they are to keep your uterus strong and safe. Only that very top layer sheds during your period.
Your uterus is a muscle about the size of a fist, and its walls actually have different layers doing totally different jobs. The inside lining is called the endometrium, and during your cycle, only the soft top layer of that lining builds up with blood and tissue. When hormone levels drop at the end of a cycle, your uterus muscle squeezes to push just that built-up top layer out. That is your period.
The deeper layers never shed:
- The base layer of the lining stays put so it can grow a fresh top layer for your next cycle.
- The thick muscle layer stays right there to give your uterus its shape and do the squeezing.
- The outer protective coating wraps around the outside of the organ to protect it.
So your body only ever clears out what it built up for that cycle, never the foundation. 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.
