Help!

Jazmyn

So I am 18 days late for AF and tested all last week with 5 different tests and 4 negative and 1 vvf positive. I went to the clinic today to see if I could get a clear positive and nothing! I'm negative and its killing me. No period , but bfn 😯. I've been cramping like I'm going to start my period and my breasts are sore as well as extreme bloating for the past 2 weeks and now with bfn's I'm not understanding why my hormones are out of wack.
