2-3 weeks: Day 1 is the first day of menses; day 14 is ovulation day; day 28 is implantation day. Depending on the woman's cycle duration and accounting for variability it could be 2-3 weeks. Sometimes, women confuse 2 days of light spotting (implantation bleeding) with a period; when in actuality, their last "real period" was a month prior.

3-5 days.: Conception occurs within 24 hours of ovulation typically and implantation 3-5 days later in most cases. As a result, the most sensitive HCG assays will detect early pregnancy 6-10 days after ovulation - with later implantation of the fertilized egg being associated with decreased likelihood of successful pregnancy outcome.

24hours and 7days: 1) Once ovulation occurs, the egg is susceptible to fertilization (conception) for about 24 hours, +/- 2) Once fertilization occurs, the time required for the egg to travel through the fallopian tube to the uterus and implant is usually between 7 and 10 days.

Implantation bleed: Implantation bleeding is much more common on the internet than in real life. It occurs rarely and exclusively in someone who is pregnant. The only way to know if someone had implantation bleeding or just irregular menstrual bleeding is to wait and see if you are pregnant. If your test is positive then this was implantation bleeding. If it is negative then it is just irregular menstrual bleeding.

Agree. I'd say implantation bleed is rare enough that you should assume it's NOT implantation without having a positive test.
