What could the discharge be that she is experiencing? ?

the mucus could mean that she is pregnant. usually, the mucus plug is formed early in pregnancy so there is a lot of discharge. my sister-in-law just went through all this and i'm trying to have a baby so i've been asking her all these questions. also, a lot of women can start having symptoms a week after conception so its not too early for her to be experiencing them. although, i've thought i was having symptoms so many times before and not been pregnant. i hope she gets the results she wants! hope that helps.
