Random pains in inner thighs at 37+3?

Maybe for the last 5 days just at random times on and off ill get what feels like a Charlie horse kind of pain in my inner thighs, anyone feel this? It can't be a kind of contraction right? It's not persistent enough for me to worry but it is definitely something new. And I drink atleast 64 oz of water a day, and doctors have said I'm not dehydrated so I'm kind of confused!
