I am getting the exact same pains! I get them on both sides, right down the bottom near my hips... and can only describe them as stitch-like pains. I had them quite bad today when I was walking to get my lunch. I am gonna mention it to MW at next appointment in 2 weeks, but think it's just our bodies not being able to cope with as much as they could before - I know I'm terrible at taking it easy and get in trouble from my mum, dad, OH and, well everyone else for doing too much! Lol My sister was diagnosed with Pelvic Girdle Pain at about 20 weeks, so I'm wondering if that is what this might be? x
