False labor scare?

Hi all, I’m currently 35+3 FTM and woke up around 1:30am this morning with severe hip/pelvis pain. I drank down 2 water bottles and tried to get some sleep, but it only got worse and I started to have extreme lower back pain. My stomach would tighten up like I was having a contraction, but this was happening sporadically. I eventually called my doctor around 4:30am when I was still not finding any relief, asking if I should go in. She told me to drink down another water bottle and take some Tylenol, which did eventually help me sleep. I woke up an hour later, and wasn’t feeling the pain anymore. Does anyone know what exactly this was? It was the most intense pain I’ve ever felt.. false labor maybe?
