How soon do you have pregnancy symptoms? what are they? sex 1 week ago , can i have pregnancy symptoms now? i get nausea and mild cramping.

2-3 weeks after sex: In general, there are no signs or symptoms of pregnancy 1-2 weeks after sex. Usually, symptoms start more than 2 weeks after sex, but only if a woman is very attuned to her body. Symptoms of early pregnancy are similar to symptoms seen in non-pregnant women, so a urine pregnancy test should be done after one's menstrual period is missed after having sex a couple of weeks earlier.
