I almost went to the emergency room because I have so much discharge that I thought I could be leaking amniotic fluid. The doc said it sounded normal so I'm waiting on my appt tomorrow to see what they say when I get my beta strep test.
Could be your mucous plug. I lost mine today and had my "bloody show". I'm 36 +3 with second child.
I have also noticed increased discharge over the past weeks. My doctor said it is very normal ( as long as they look to make sure there is no infections). If it increases you could try a panty liner.
