What cause mood swings? How can I give a hand someone with it?

Sounds approaching a yeast infection. If you're in no rush to go to doctors, try Monistat for the the itching..if that doesn't facilitate things then run to the doctors and get tested to see if you enjoy a urinary tract infection or maybe an STD.

Could it be?

You did not say-so if this happened after have sex, but I guess it did. So the possibilities are that you have some sort of an infection, any a yeast infection or some other STD. My advise is to abstain from sex until you see a gynecologist who will fashion some tests and administer you medication. I do not believe you yourself can do anything to cure the problem.

Who makes the most accurate home pregnancy experiment? How much do they usually cost?

See a clinic as soon as possible. Sounds like a STD to me.
