FTM: Am I having contractions or am I crazy??

The short question is: is it possible to experience contraction pain only in your upper inner thighs??

I’m 38 + 1. The pains started about a week and a half ago. It started out as mild discomfort every now and then, nothing major. The last three days however the sensation has been increasing in frequency and intensity. It’s now maybe every 15 to 30 minutes and it’s PAINFUL. Like stop me in my tracks, use the F word, double over painful. The pain starts, builds, then subsides but I only feel it in my inner thighs. I feel absolutely nothing in my abdomen or back.

What the heck is going on???
