How long does it take for pregnancy symptoms to occur?how long does it take for implantation?is the egg fertilized before implantation?

2-3 week. 1 wk. Yes.: Women who are very attuned to their bodies can feel pregnancy symptoms from a pregnancy at about 2-3 weeks after ovulation. A woman can sometimes feel symptoms just before when her period will come (but the period doesn't come because she is pregnant). Implantation happens about a week after ovulation (that does not mean the embryo sits on the uterine lining for a week in order to imbed itself).
