Inner thighs cramping?

Ba

So, to start, ftm 33w2d pregnant. I have been noticing over the last week some mild pubic and adductor (inner thigh) pain which I assumed is spd/pelvic girdle pain. I can live with that and i do exercises for it. However, when I go for a walk my inner thighs seem to be spasming and sometimes it catches me so off guard i have to stop in my tracks. Has anyone else had this? Is this a sign the baby is dropping into the pelvis and pushing on nerves? I figured I would bring it up at my next appointment, but that isnt until next Friday.
