Hey there- completely normal!
Vaginal secretions do change while pregnant- some women even have to wear a pantiliner so they won't soak themselves. It's more prevalent in the first and third trimesters.
Also- you are still very early. Some women don't start to experience other symptoms until they are 6-7 weeks along....some even later. Haha, one of my friends from back home didn't find out she was pregnant until she was six months along because she had virtually no symptoms and still got af- she thought she was just getting fat!
