30 weeks having crotch pain

Christian

Im 30 weeks pregnant and currently i am having pain for about a week now with movement in my labia. It happens mostly when i turn or go up/down stairs and typically the pain is in the labia i am turning towards. Its starting to happen when i am sitting or just plain walking. Sometimes i feel an intense pressure with the pain. Is this just from baby's position? Any idea what can help the pain? I hope this post makes sense its kinda hard to explain.
