D.S.
I had this happen- I was older- sometimes its just menapause kicking in real early believe it or not- I was about 38=39 when it started- I suffered for years- FINALLY! I had an ablation done- I was done having children so it was ok- but just see what the gyno has to say and if they recommend an ablationa dn you are done having children- its mentally a life saving choice- the periods were ruining my life.
Also- if you ahve been stressed lately- that can bring it on as well- the clumping isnt the concern- the length of the period will concern the doctor- keep a chart
