UTI and pregnancy

Sucks!!! Its so damn painful. Shit I thought something was wrong I got up and my stomach was hurting then my back starting cramping. I am thinking oh no this can't be happening. I go pee and it doesn't burn when I pee so indication of an UTI. I gathered my things and went to the ER quickly. First thing I am dehydrated as Fuck so they couldn't get an I.V. started so I get stuck 3 times before they can find a vein. Next I get a shot in the hip or the ass whichever you prefer that burns like heck. I am worried at this point about my baby. The shot was for nausea because I was super sick to stomach from the nerves. The came and said we have to use to find the baby's heartbeat. I asked her what was it lol?? Yall I swear it looked like an old fashioned EKG machine. She was explaining to me that some lady had stolen their fetal doppler. I laughed and she proceeded to find a heartbeat. There was no heartbeat nothing but static. Sooo I am worried at this point freaking the fuck out to be exact. The nurse was upset too because she's usually good at finding the heartbeat. She was like its probably because the machine so old they would do a ultrasound. I was kinda relieved but still in a lot of pain. So hours of waiting they took me down to Ultrasound and got to see my little sidekick he was kicking and moving all around. The technician slipped and said he so happy. I said he she said yea I am certain but don't tell them I told you because you came in for an emergency. She even let me see him he was moving all around. 😍😍😍😍. I was relieved but yet still in hella pain. So I am wondering what heck is wrong with me and where the pain is coming from. My mind gets the wondering about STDs and all type of shit at this point. Hours passed and they discharged me and told me I had an UTI and nothing is wrong with Baby and everything is great with Baby. I was so worried and the pain was the worst.
