Could it be a blood clot? I Googled "inner thigh pain pregnancy" and had some scary !!!Blood clot!!! results. I don't even know what to look for..
I called my doctor's office, which is closed and leaves no number for emergency/worrisome scenarios. Just a message to go to the ER if you're faced with something frightening.
For what it's worth, I'm 29 weeks. The pain is very similar to a bad bruise or a pulled muscle. I haven't done a single strenuous thing in the past few days aside from minor Christmas shopping and waiting in line for an hour for my child to see Santa last night, which I would hope wouldn't result in terrible leg pain the next day. The pain is not in my groin area or in my knee. It's almost exactly in the middle of my inner thigh.
