Gyneacological - During my period I use a tampon and most times when I remove the tampon there is a section on the tip of it which is fluro yellow/green. This does not show on the first day when my blood flow is heavier. I typically have irregular periods, lasting about 3 days, first day heavier then the other two much lighter. I have severe endometriosis and am looking into surgery for that this year. I am 40 years old with one child who is now 5. This color on the tampon has appeared since having my child. I do not know how long I have had the Endo for but I suspect decades. I mentioned it to the GP but he seems unconcerned.
