What's wrong with me?

My period is 3 days late almost... Which isn't unusual but seldom happens... I'm bloated and cramp at times... I also have clear discharge... Normal smell... I started dieting 3 weeks ago limiting my calorie intake to 1200 a day I lost 11 in less then 2 weeks... Idk if that's the reason my period is late and my stomach is bloated... I don't think I'm pregnant since I been exercising at low to high intensity and nothing has happen... I had sex once like 3 weeks ago but the condom broke and nothing really went on from there.. As please help idk what's wrong I just sure hope I'm not preg
