Thanks heaps for your replies. I didn't use it last night but have just been to the dr and he said it is ok to use.

He also said I can use vicks on my chest. I hope that's ok....

I started to panic a bit last night because bub didn't move like usual. I didn't feel any movement all night and then only one tiny one this morning. Dr checked heartbeat and all is fine so that is good. I just have to rest up and try and get better.
