Endometroisis is more common than you would think but they find it lapryscopically, which means going inside so doctors don't like taking that route unless it's unbearable pain. Birth control is supposed to, and known to help it. I was diagnosed with it.
Also, those are a lot of symptoms of cervical cancer but don't get yourself scared. It's no were near being like heart cancer, you have time to find it.
Doctors don't like being told what to do, but if you have family history of the cervical cancer it's mandatory I would think to get checked.
Your best bet is making an appointment with a womens doctor because there the most knowledgable with whats going on but don't worry yourself to crazy.
Also you are liable to stomach ulcers, but you shouldn't be bleeding from them and you are also liable to check if it is an ulcer.
Plus it could just be the pill your on, periods do suck but there like a self cleaning oven for your vagina, I'm on the pill as well.
