How can I get period to come

I’m 12 days late I know I’m not pregnant I took two tests they both came up negative, I know it’s not my diet because it’s very balanced and not really stressed either about I’m not sure what’s going on with my body.

My boyfriend wears condom every time we have sex but I have notice white discharge it’s really watery right now

I just wondering what you guys think about this ?

11:17 I just got my period !!!!! 😊🎉🎉
