2 weeks late negative tests?!

Hayley

So I’m 2 weeks late on my period and I have taken multiple tests that are all negative what should I do? I’ve been having a few symptoms like a couple of times I’ve felt really sick like I’m going to throw up and I have thrown up on some occasions. Really sore boobs. Feeling dizzy and nauseous. Headaches and back aches but that’s about it a few cramps here and here too!
