did I conceive

Anon
My fertile week started Sunday. We didn't pull out Sunday. On Tuesday I had really thick jelly like discharge, and on Wednesday it thinned to a more stretchy clear discharge. Immediately all my discharge stopped on Thursday and today, Friday, still dry. Very very dry. Did I ovulate in the beginning of my fertile week? Usually during my fertile week I have a lot of discharge the whole time. Could I have conceived?
