Talk to me about SPD?

Im 25 weeks pregnant today and I've been having tons of pain as my belly grows, but the worst is how bad my hips hurt at night when I try to sleep. I constantly have to turn from one side to the other because the pain keeps me up. It feels like I have terrible bruises on either side. Then my hips feel fine during the day. I've also been struggling with sciatic pain, but yoga stretches that focus on that seem to help alleviate it if I'm consistent. I have had tons of "lightening crotch" already too :/

I want to add I've always slept with a pillow between my knees, but it's not helping my hips at this point.

Is it possible that this is SPD? I'd never heard of it before (3rd pregnancy, 2nd baby- I didn't have these issues with my first).

Thanks for any information! 🥰
