Back cramping

I’m 38+1 and baby has dropped, my hips/groin are sore and achy. I’ve been having 2-3 BH contractions an hour - sometimes they hurt a bit and sometimes they don’t at all. But just now I had intense cramping in my lower back that lasted about 2 minutes. I felt my stomach tighten too, but didn’t feel any pain in the front. I don’t think I really even have a question, who knows when she’ll come…I’m just anxious about her arrival. Everything thing I feel, I’m just like ooooh is this it? It’s hard to be patient.
