Opinions please.. (bit long)?

It could be one of many things. For one if you are stressed out that can make your period late. Also if you have ovarian cysts it can cause pain. But the fact that you have taken tests and there have been faint lines can be that you are pregnant. Do you have a regular physician? Because you could call them. Even if there is a walk in clinic where you are living you could go there. Planned Parenthood would be a good option seeing as you dont need a doctor, if you look them up and give them a call that would probably help. Being 17 days late I think you should be getting an absolute result by now. So there may be other things going on. Good Luck!
