I only have 1 child, but I had them quite bad! - they gave me pethidine and a massive compression band to put around my tummy & hips.
All through my pregnancy i joked that i must be having twins because i was huge (though measured exactly right). When i got AB pains, i seriously thought they had missed the second baby and started to panic i was going to have 2 to look after!
Some people get them, some people don't. Some people get them quite bad, others its not so bad.
Don't worry too much about them, it still doesn't hurt as bad as labour and you wouldn't not have a baby just because of them.
If you keep getting heaps of comments maybe you should tell them "thanks for making me worry about more pain!!"
Goodluck, i hope you don't get them!
