Aiyoh, this is so normal lah, during pregnancy the discharge memang becomes more, and the consistency changes like that (creamy, stringy) depending on your hormones and what stage you're at. A few of us mummies compare notes and we all had similar experiences, nothing to worry about unless it's coloured (green or brown), smells funny, or you have itching or burning. But since you're already 11 weeks, best to just mention it to your gynae at your next checkup for peace of mind, okay?
