I had loads of stretching pains in the 2nd trimester. Sometimes stabbing pains, sometimes stitch.
In fact the DH took me away for the weekend at about 24 weeks and I was in agony every time I walked, however slowly. I really looked like an OAP all weekend, even just walking really slowly it hurt. It was mainly down low around the pelvis area and it stopped when I laid down.
Hopefuly this is what you had hun.
