I had it with 1st preg from around 30 weeks... no sign of it yet this time.

Go and see a physio, b/c even though they can't get rid of it (it's hormonal), there are some stretches which can help, and you can get some splints to wear at night which really help. I found if I used the splints at night then it wasn't so bad through the day, and I wouldn't wake up with the aching or the pins and needles.
