I feel like I've posted a lot today on advice but ladies can you help me out here? I went to the doctor 2 weeks ago and was dialated to 1 (no big deal) but today I feel like she's sooo low, pressure when I stand and walk, shooting pains up in my area and the muscles in between my legs have gotten so sore today that it's a struggle to even move my legs when I'm sitting or laying down to get up. Like spreading them hurts. Haven't had sex, and no physical activities other than walking. What is this?? I'll be 36 weeks tomorrow.
