Is this SPD pain?

27+1 today and I’ve started having pain in my pelvis near my vagina. If I had to describe exactly where it’s hurting, I’d call the area my seat bones (Horseback riding term, sorry! But it’s a perfect descriptor, like I’ve been sitting a trot for the first time in a while) which I believe is where SPD pain is located. I’ve noticed it most when I stepped out of the tub this morning, lifting my legs to put on pants, and when I open my legs while laying down on my side (like when rolling over.) I have an OB appointment on Monday so unless it gets worse, I’ll just talk to my doctor then. Baby Girl is still moving around like normal so I’m not especially worried.
