Really worried

Hi!!

I have a question!..

AF was due on June the 14th.. still no sign of it! But have got sore nipples.. headaches.. feeling sick.. very emotional! Now I have been pregnant before and these are very much like the symptoms I had before except I have no positive test!!? I've took a test before af day of af 3 days after and now I don't know wether to test again!.

Previous pregnancies I have had positives up to 5days before my af was due.. now I am late and negative tests! What's going onnnn??

Thanks xx
