Go for a walk - I found walking around the house eased off the cramps.

How far apart are these contractions? I found this type of practice contractions started around 37w like this and I wasn't happy to have them for 5 weeks!

The discharge could well be the start of the mucus plug going, but it's normal to have extra mucus in pregnancy.

If the cramps don't stop, get worse, or if you're worried then can you ring your midwife and ask her advice?
