Well hun, for every women that is different so that is hard to answer.
I know some women that never got a symptom throughout their entire pregnancy that they noticed other than their missed period.
I on the other hand, had symptoms about a week before i even missed my period, which would have made me only 3weeks pregnant (generally 1wk after conception, but that was me) i had sore breast and a slightly higher temp, and period like cramping)
Generally speaking most women get symptoms about 5-7wks usually Fatigue and sore breast are the main ones. Good luck with everything.
