So confused

So I took a test about 4 days ago and got a vvvfl. I FEEL prego. My breasts are tender to even touch. I'm beyond normal emotional. I was supposed to start yesterday and not even a sign of starting. Took another test this morning and NOTHING: ( I don't understand what is going on. I might add that last night I had a super sharp pain in my lower abdomen that lasted well over an hour. It had me doubled over and I could barely move. Thoughts please??
