Help (TMI)

So I've contacted my obgyn and even my fertility specialist and they don't seem like it's anything to worry about... but I've been bleeding for 3weeks first week was kind of normal came when my period was supposed to but was way heavier than normal then stopped for two days tried to enjoy sex with my husband and he freaks because I'm I'm bleeding a ton that started the next 2weeks of very heavy bleeding with dimes sized clots. Well I stopped a day ago and feeling around and I have large lumps that are painful to touch on my cervix and now I'm bleeding lightly again. I took a test not pregnant. I'm really worried something is wrong but no one is taking me seriously. Please tell me I'm not just over reacting.

Edit-

Doctors stuck me on progesterone. Said it's no big deal and stop over analyzing this. They will not make an appointment to see me but will answer questions through the phone.
