A little update - Rang the hossy and the MW told me as it wasn't happening during the day then it would only be water mucus and there can be a lot during preg. She said to wear a pad and if it gets really wet then I can take it in for testing again.

I must say I felt as though she was rushing me when I was talking, I tried to explain what had happened when I went to hossy on Fri morning, but she just cut me off and said 'yep yep yep and...' I had such a good experience at this hossy with DD, but I didn't have anything out of the ordinary with her. I'm not feeling very confident with them there at the moment... Nothing I can do about it though, the joys of living in a small town!

Thank you all for your advise. I will just keep an eye on it all and see how we go from there.
