I am a 31 year old female and I have had my tubes tied 6 years ago. This is the first time it has happened but I am currently on my period and I am experiencing heavy blleding and huge blood clots. I have gone through 3 super tampons in just about 2 hours today which is very abnormal for me and I am having to wear a pad as well just so I don't leak through. And the pad is covered pretty thick as well. When I use the restroom even when I have a tampon in I am losing huge blood clots about the size of baseballs. What is going on, could it be anything serious?
