How far along are you? If you get yourself a BB ticker it will be at the bottom of each of your posts so people can see how far along you are.

As for the discharge. Hormones are the likely cause. I also had more creamy coloured discharge since being pregnant. Although not so much that I needed a pad until recently. I don't have itchy or soreness either and their is no smell so I don't think its anything nasty just hormones. BUT if your worried you could ask your GP to do a swab and double check.
