hi ceolas
i ha d spd really bad after dd3 (my number 5) and it never fully went away.
im now 7 wks pg with numer 6 and have started getting twinges already!ive also got the clicking/grinding thing going on when i move or get out of bed.
ive bought a support belt aleady and we are going to get one of those memory foam mattress toppers.
i have also started sleeping witha pillow between my legs and im thinking of getting a body pillow aswell!
see your gp and ask to be referred to the physio,they can give you lots more help and advice!
