Confused..

Sweta
My period was supposed to start yesterday and it hasn't.  I'm cramping my back hurts but no bleeding.  
I took a hgc test this morning and got this....  I have been trying to 3+ years and I got excited when I saw this but I'm not sure as the line is faded.  I'm nervous as crap...😰😰😱😱.  What do u think ladies ??
