I'm 25 weeks and in the last few days I have been feeling this pain on my pelvic area and inner thighs. It feels sore like how it feels when you do exercise and the next day everything hurts, that's how it feels. When it comes to sleeping it's worst and when I try to switch sides it just hurts and my butt feels heavy to turn 😆 but stretching and doing a squat feels so good lol I hear it can be several things like the position of the baby, and the body just stretching as to prepare for birth. If it feels like this already I can't imagine what the next few weeks will feel like 😦
