My local maternity hospital told me I wasn't in pain when I went in there in threatened pre term labour.
At 28 weeks I felt like I was having a massive period. But, no, there's no tightenings - you're not in labour. They were all down low, not where they put the disk on my belly. My uterus wasn''t even up that high!!
31 weeks my back was cramping for about 30-40 seconds at a time and hurting like biatch, but I wasn't in pain or anything, apparently, because it wasn't showing up on the CTG.
Mind you, they flew me to Melbourne anyway. lol, but by the time I got there everything had basically stopped. But I was still getting back pains and period pains.

Keep strong, honey! You'll get there.

Have you been having steroids??
