Excruciating pelvic pain

Im34 + 2 and I’m the last week I’ve been in ridiculous pain. My pelvis feels like it’s going to snap/shatter- it doesn’t seem to make a difference how I sleep or sit or walk, it just never goes away.

A week ago (when it started getting worse really) my midwife said the head was extremely low (literally, all but engaged), I have another check up in 7 days time but I’m not sure if I should wait that long to contact her. This is excruciating, I’m starting to wonder if it’s a normal amount of pain for something like this. I’m at the point where I cry quite often through the day because I’ve moved the wrong way slightly. I have a high pain threshold (delivered my first without any pain relief) so this is stressing me out. Help me, pleeease
