Try not to worry Dollybird, I had a few weeks like that, was just a really heavy feeling down below, midwife said it could be spd, I bought a maternity belt from Mothercare, it was only £12.00, I dont use it all the time, but when I take the dog out for long walks, I pop it on and it does help relieve some pressure, but if your concerned, see the midwife, also better for peace of mind. I also have had no movement yet, I have been checking with the doppler every couple of days and she seems fine, I just cant wait for the movements then I can relax, 19 weeks tomorrow, never did I think I would be here, roll on July. I hope everyone else is doing well.
