I am just starting my period for the first time second day nothing will come out on pad but when istick a tampon in blood it why is this?

When you first start your period, your menstrual flow may be light and irregular. This is normal and is because your body is still adjusting to the hormonal changes that trigger menstruation. In some cases, you may not see any blood on your pad or panty liner at all, but you may still experience cramps or other PMS symptoms. This is because the blood may be collecting in your cervix or vagina and not exiting your body yet.

When you insert a tampon, it creates a vacuum that helps to draw blood out of your cervix and vagina. This is why you may see blood on your tampon when you remove it, even if you didn't see any blood on your pad or panty liner.

It is important to remember that everyone's period is different and what is normal for one person may not be normal for another. If you are concerned about the amount or consistency of your menstrual flow, you can talk to your doctor or other trusted health care provider.
