As long as there is no pain or itchiness involved, it is reasonably safe to assume that what you are experiencing is just increased cervical mucus that many women produce during pregnancy
. Your body has to create a mucus
plug to seal the uterus once a pregnancy has been established. Increased cervical mucus is something that can be experienced during any trimester, or in many cases, all of them. Most women complain of an increase again however, during the last month (or so) of their pregnancy.
