I got my period on Sept13th and ended on the 17th. I've been having a small amount of yellowish/white discharge lately and I haven't had my period yet this month. Is this a sign of pregnancy?

So how many day cycle are you on ? When is it due, if late, how many days, it roughly does not really seem late yet??

But if you are having sex, of course you could be pregnant, the discharge sounds more like an infection of some sort.

You have to be 2 weeks, late for period to begin testing, then use first urine of the morning
