I don’t know what to do 😩

I’m 34 + 5... I went into my doctors on Thursday for NST because I was having a lot of Braxton Hicks and wasn’t feeling too well (headache, dizzy, tons of pelvic pressure and more) my doctor noticed little man wasn’t moving as much as they would have liked so they sent me for an ultrasound. We passed the test after 45 minutes of shaking and poking my belly to get him to move. Now on Sunday I ended up in L&D because I had 13 contractions in an hour (I have bloomlife so it tracks them for me) once we got there I was having a contraction a minute. They put me on an IV for fluids and tested for UTI. The quick test came back with possible uti so they sent me home with antibiotics and said the contractions should stop soon with the medication. Well I got a call today and was told to stop taking my antibiotics because I DONT have a UTI. I asked why I’m still having contractions and the doctor had no freakin answer. She just told me to drink something with electrolytes and make sure I’m having enough potassium. Both of which I was already doing on top of my over 100oz of water a day. These contractions woke me up from a dead sleep last night I’m freakin tears. But then they’ll go away for a little so I can’t call L&D cause they stop and don’t stay steady. I have an appointment today but I’m getting so frustrated. Nothing is stopping them, they’re coming full force sometimes and my baby is hardly moving through the day 😩 I feel like something is wrong and nobody has the answers!
