So Distraught & Disappointed

Haven't blead all week, & this am I go pee only to see a hint of blood?. Today would have been my last cycle day. My period was suppose to come on the 4th of August. Had all the symptoms increased appetite,belly line dark and increasing breast bigger, my current child has been stuck like glue to me... I went to ER this am scared that maybe i had a miscarriage they did a pee test and a cervical exam only to find out it's my Af starting. I'm so hurt distraught & disappointed. On top of that the nurse was SOOOO RUDE !! I was literally balling crying and she's asking why didn't I but a cheap hpt like really lady ? So insensitive ? so here I am once again false alarm. I had just downloaded the wedMD prego app dreaming of my due date and now nothing. Should I still go get a blood test??? So sad man
