How soon you need to take pregnancy test after having symptoms?

About 6 to 8 weeks but everyone is different Do you mean when do you get a bump or when do you get symptoms? I'll answer both, although both are different for everyone... In general, you start to get a bump around 4 months pregnant, although some people get it before then, others after then and some don't ever really look pregnant You can get symptoms of pregnancy as early as 2 weeks after sex, although this is quite rare. In general, the first sign of pregnancy is a missed period. The other symptoms, such as sore boobs and feeling sick can also be signs of your period coming. Most women start getting symptoms around 6 weeks pregnant
