So I'm 25 weeks. I've been getting since yesterday, a feeling of achyness and pressure really low into my pelvis. I have also been having pains, the baby is moving fine, seems lower though. I also suffered from severe heartburn which has also eased off if that could be linked? I have unbelievable lower back pain to. Any ideas? My backs agony and this heavyness in my pelvis is making me walk like a penguin! This is my 2nd and never experienced this with DS1
