BFP! Hoping our bean sticks!!!

Gabby
Took a HPT yesterday evening- BF(aint)Positive!! Took another this morning with FMU. Line was a bit darker- eek! 
​Yesterday's cramps were different than my normal imminent AF cramps- they were a lot lower and sharper, like pangs I guess. My tummy muscles around my belly button feel like they have also been cramping some, like they are pulling/stretching! AF wasnt due until Monday, so it's still fairly early.  I'm hoping the lines keep getting darker! I put in an appointment request for bloodwork, hopefully my doc can see me this upcoming week. According to Glow and my last period, I am about 3w6d. Still in shock!!! Just praying with all my might for a sticky bean!!!??
