I'm 5 weeks pregnant with no.4, and had the worst night's sleep I've had for a while last night. I was woken up in the early hours with incredibly painful, tinngly cramps in my lower legs - the only thing that helped a little was circling my ankles. Have never had anything like this at any stage in pregnancy with dds (or when not pregnant), and wondered if it was something associated with pregancy or unrelated? Any advice would be appreciated as I'm dreading it happening again!
