Hard bumpy Cervix

[Sarah25952]

I'm a twenty year old who has only had one partner who has only been with me, I have had clean paps for the last four years, the last one in July, but I have a hard (harder than the end of my nose) cervix, and it has developed a bump. I first was concerned when I realized that I am leaking a pure white very thick vaginal discharge a whole table spoon or more every time I go to use the bathroom. I never had a hard cervix before, not even after menstruation, and the "lips" of my cervix now feel more open than they ever have before.  I started using a diaphragm a few months ago, and I had a bad reaction to the spermicide, so now I only use it once a week. Is this just a bad reaction to the diaphragm, or should I be more concerned? If it is a bad reaction to the diaphragm, can this cause me infertility? Also do you know any spermicides that can be used with a diaphragm that do not contain nonoxynol 9? I'm in Europe right now so even if they only sell it over here I can get it. Any help or advice you can offer me on this subject would be greatly appreciated.
