Hi! I am a 28 year old. I have always had regular periods. But about 3 months ago, I experienced very heavy bleeding for several days for the first time. Then it stopped and gone back to regular for 2 months. This month however, my period started as regular, but then when it supposed to die down, it started heavy bleeding with many large blood clots. I now need to change a super tampon and a heavy flow period pad every half to one hour. I have also taken Mefenamic Acid to try to stop this, but it does not seem to be working. Can anyone help please? Thank you.
