Stressing Currently 31 wks and 1 day

Okaay so 2 fridays ago i went in to L&D for contractions at 29+3 they gave me vistaril to calm uterus and fluids over night (2 bags) and it didnt help they did a cervical check i was 1/2 cm 50% effaced -3 station did a protein swab came back negative. fast forward was suppose to follow last monday with OB but couldnt so had to go back in to be monitor again everything still the same. Fast forward to tuesday lost my complete mucus plug (i know itll grow back but its was just alot) came with a little cramping and pressure but just didnt feel like going back to L&D. Last friday ended up going back in because i was dead asleep and woke up with really bad pain in stomach got up peed took tylenol went back to sleep. woke up still hurting called my fiance outta work went back up and still nothing. they prescribed me vistaril. so now last night (12:43AM currently) and i swear the amount of pressure in my stomach was uncomfortable and so frequent. it went away for a maybe 45 mins and came back with actual contractions. i just dealt with them because the medication i was prescribed makes me tired and my 15.5 month old waa not ready for bed yet lol. so i gave her a bath after they subsided and after that it triggered them but didnt last very long. well about 11:22pm it started all over again took one of the medication and went to sleep for 30 mins woke up and they started alll over again idk if i should try amd take another one or just try and sleep them off. side note the pressure is just as bad when i get up to walk and i try switching positions which kinda help but not as much. so one please tell me these are just braxton hicks. i have an appointment thursday this week and im just trying to hold off going to L&D.
