CM / fertile, before and during pregnancy, vaginal discharge

I am 8 weeks pregnant now. I have been experiencing a sudden increase of the amount of CM my body is producing. I have been told by a lot of other women who have children, and others that are expecting as I am, that it normal for me to have different CM now, then I did before I got pregnant. It seems to me as I am having a vaginal discharge because of the constant flow. It is clear, very stretchy, slippery with areas of white. It does have an odor but it is not foul. Why am I producing so much CM now, or do you think it is to having sex, or maybe I have some sort of infection, therefore vaginal discharge. I also have kind of a stupid question, is my CM the same lubricant my body produces for sexual intercourse, when I get wet when kissing and touching, lubrication for my bf to penetrate me?
