@marnie1997– Welcome to Mayo Clinic Connect Leukorrhea is a discharge that can be caused by several things, pregnancy is one, hormonal changes where there is more estrogen, and infections. When I was pregnant I had a lot of discharge. Since your concern seems to be whether you are pregnant or not I would call your doctor and get a blood test. This way you should have a definite answer.
How late are you? I hope that you will be happy if there is a positive outcome!
