Am I pregnant?

I have never been pregnant, EVER. My period is late by an estimated 24 days (could be a little less, or a little more. Couldn’t exactly pinpoint my last), and I’ve also taken two pregnancy tests (both negative). I’ve been craving anything/everything, which is off for me because I’ve been losing weight like crazy/with no appetite. I’ve tried to get sexually active twice in the estimated 24 days, and it’s been a little painful. I’ve also been urinating very frequently, and discharge is abnormally a lot (than usual). Please help?! Also, I know I’m stupid for this, but I haven’t been on birth control for about 2 months).

My sister thinks I’m just having a really weird cycle... thoughts/concerns PLEASE?! 😥
