Unfortunately worry is human nature. Good luck with all the female stuff. I had fibroids & precancerous cervical cells...a couple years later I ended up with a hysterectomy for adenomyosis & they found cervical cancer when they biopsied my cervix post surgery. (I think I spelled it right) Anyways, look it up. It may be of value to you with your heavy periods & pain. It put me through H-E-double hockey sticks for 2 years.
As far as the worry over lymphoma, I wish you the best. The best advice I can give is not to worry needlessly until you know. Of course here I am worried sick about my 7 year old who unfortunately, shows enough symptoms that his doc shows concern too. I guess I'm not so good at practicing what I preach, but for what it's worth, I wish you the best.
