Discharge is normal, only time to be concerned is if its accompanied by odor and itching.
Oh hun its totally normal, thia is my third pregnancy and with all of them straight away I had a discharge, only solution are panty liners :)
Increase in discharge is normal the closer you get the more you usually see
You will get more discharge the further you go panty liners are the key. As long as you don't see a lot of bleeding everything should be ok a little pink is ok too.
