Me and my boyfriend had sex just about every day after my last period.. and he nutted in me every time.. now I have this white milky discharge... is that a sign of pregnancy?

The first symptom of pregnancy is a missed period.

He "nutted" in you? How disgusting to hear. How about he ejaculated.

Is your period late? When is it due?

Well I prefer nutted.. but my period in 3 days..

Nutted, I am so happy you feel so low class and have no respect for the English language and for yourself, that you are happy referring to sexual act in such vulgar terms. I am sure your sex life is filled with joy of such.

Discharge can be a sign of many things, or just nothing, often infection or STD.
And of course pregnancy.

If not period, wait 10 days to two weeks and do a pregnancy test.
