Has this happened to anyone? Need some advice please

BERNADETTE • I`m blessed with a beautiful boy named Xavier and engaged to the most amazing man and his name is John♡
I'm having all the symptoms of being pregnant like, Boobs are killing me, extremely bloated, breaking out, really tired, cramps and nauseated..... I've taken a million hpt's and they all come back negative. I'm suppose to start this Saturday (5-2-15) I'm not sure what else to do. Maybe do a blood test? Any advice?
