I didn't have a lot of discharge for my 2nd week of the cycle and i should start my period tomorrow. i have had creamy white discharge and it changed to watery clear discharge. is this normal, or a sign of pregnancy?

A balancing act ;-): In our bodies, the "normal" vag d/c gets watery if the germs over-grows the yeast; it can smell bad, too. If the yeast over-grows the germs, the d/c gets thick and itchy. The names are bacterial vaginosis, or bv, when the germs over-grow and candida, when the yeast over-grows. Often thought of as infections, but really just an imbalance. See your doc to get the rx you need.
