You need to just take her because this sounds like it could turn into something serious if it has not already. It may be an infection, tubular pregnancy, ovaries etc., there are just too many options. But it is obvious it is getting worse, and to wait months is way too long already. Women hesitate to go sometimes for female problems, but hopefully there is a female doc she can see. I hope you can help her and find out what it is. Good luck, and take her yourself if you have to.
