pregnancy scare... kinda?

went to the dr last week for my iud, she took an ultrasound/sonogram/whatever to see where my uterus was.

she says, “oh, your bladder is full!” and in my head i was like uhh i don’t feel like i need to pee? and then she asked if i felt like i needed to pee and well,

dr: do you feel like you need to pee?

me: no..?

dr: oh! you know what!?!?..... *10 second pause* it’s a cyst!

i swear i about passed out when she paused; singlehandedly scariest moment of my life so far.
