I have had SPD (pelvic girdle pain) with both my pregnancies. My second is just over two weeks old. I've been getting mixed messages from the midwives about whether breastfeeding extends the amount of time I would suffer from the pelvic pain or not. Some say it does as the hormones don't return to normal until you stop breastfeeding, but some say SPD/PGP is purely a 'mechanical' problem so breastfeeding has no impact. Would really like a definitive answer on this. Does anyone know about it, or had a good evidence-based explanation from someone?
