Is this SPD????

I think this is what I’m dealing with. Started yesterday and it’s so painful I can barely walk. 38 weeks today. Being induced at 39 weeks if I don’t go into labor sooner, because I have another big baby on the way! Anyways, I didn’t deal with this pain last time and Idk how I’ll make it a week! I can barely walk and I have to chase my toddler around. Anybody else dealing with this?? It’s like a punching burning pain in my pubic area. Only relief is when I’m sitting down.
