Stupid stupid stupid.

So I called out of work due to pain in my lower abdomen. I am 16 weeks pregnant. I went to Urgent Care because I'm sure I have a UTI and a yeast infection, but AS SOON as they heard the words pregnant and cramping together they refused to treat me for either!! Said I needed to go to the ER. Like excuse me, I'm sure the cramping is due to the UTI. So here I am, not going to work and possibly get fired because they wouldn't give me a doctors note. I refuse to pay 1300$+ to get treated.  😡😡 My doctor always tells me to rest when I call her. So would it be wrong of me to show up at my doctors office Monday morning and refuse to leave until I'm seen????
