Completely normal and for me it gets worse if I get too hot or the air is too dry. A cool mist humidifier helps if you feel they are getting out of control.
Oh yeah its the hormones and increase in blood volume!!
Normal! I did this with my daughter and Im now pregnant with second baby and it is happening again. My dr told me to try sleeping with a humidifer and it helped tremdously. It is just caused from your nasal membranes swelling and/or being irritated. Another weird pregnancy symptom. ;)
