I am losing weight very fast and i'm kinda worried?

I am a 21 yr old female i stand at about 5'3 and am now 185lbs but a couple of weeks ago i was 195 and im just a little worried and want to make sure this isn't a sign of illness. The only thing i have been experiencing is some breast soreness and a little nausea here and there and i get kinda tired in the evening time i dont kno if that has anything to do with it but anyway....i play tennis for about 1-1 1/2 hours a few days out of the week but i havent played that much recently and i dont really eat that much either but at times my appetite picks up. At first i thought i was pregnant but i started losing weight so now i dont know what to think about that, but if anyone can help me it will be greatly appreciated thank you and God Bless


Thanks In Advance!!!

I would see a doctor. If you did not just start a diet and/or exercise program, something could be wrong.

However if you just did start a program this amount of weight loss is normal.

Either way you need to see your doctor.(because when you start an exercise program your doctor should know)
