36 weeks with immense back pain

Kayla

So today I’m 36 weeks and 2 days, we had a weight check ultrasound on Tuesday and he was measuring almost 3 weeks ahead and already with an estimated weight of 7.5 my first was induced at 39 weeks and I ended up having a csection due to failure to progress (17 hours of being stuck at 1.5 centimeters with pitocin) I’m unsure if these are contractions but they are intense and I’m not sure what to do. Any advice would be appreciated.
