Louise my SPD got worse after Evie's birth and was worse for about a week or so after, the physio said before I had her to expect it to get worse for the first couple of weeks, not only because of the trauma to your pelvis from birth but also the hormone that relaxes everything doesn't start to disappear for a couple of weeks afterwards. I had physio at 4 weeks pp as the pain still hadn't gone and my leg was going from under me still and she said it can be bad up til 6 weeks and even then it might remain until 6 months pp! Fortunately mine has all but gone, but with the occasional flare up. I hope it's better soon and you've been enjoying those newborn snuggles, she's soo gorgeous!! The pics of her had my overies aching last night!!
Jelly I hope you and JJ are better soon... eh twins, how would you feel about that?!
