How long does it take to get pregnancy symptoms. ?

3 weeks after sex: Women who are very attuned to their bodies can feel pregnancy symptoms from a pregnancy at about 2-3 weeks after ovulation. That's approximately 3 weeks after sex. A woman can sometimes feel symptoms just before when her period will come (but the period doesn't come because she is pregnant). Implantation occurs about 7-10 days after ovulation if conception happened.
