Hmm, just read about SPD on another forum and it all sounded a bit familiar! I am 22 weeks pregnant and have been getting lots of really bad pains in my groin. It felt like stretching sort of pains, almost like period pains or when you have a stitch. I also have had quite a bit of aching pain in my lower back for a few weeks. Occasionally I get a stabbing type pain in my pelvis. When I stand up quickly it hurts at the bottom of my stomach/top of my pelvis area. Today I went for a longish walk and was getting the ache spreading up and across my hips. I have a history of 'clicky hips' from when I was a child (which I forgot to tell my midwife about, doh!) As my baby has been quite active I haven't been too concerned that the pain is a sign that something is wrong with the baby and just put it down to very bad stretching pains, but no that this must be common in pregnancy (this is my first- I keep saying "I never knew being pregnant would hurt so much!" Does it sound like this could be SPD?
