If a woman has had an absence of discharge for a couple of weeks does this mean she is pregnant?
No it doesn't. During pregnancy a woman has a increase in vaginal discharge, not a absence in it.
Well, yes, it could be. After my period, around my ovulation time, I had very little discharge (if anything). I believe it was because the egg took and became fertilized. I am now 1 week pregnant, and still have very little discharge. Everyone is different.
