A member asked:

How long after sex does it take for a sperm to fertilize an egg? and how long does it take for pregnancy food cravings to occur?

A doctor has provided 1 answer

Sperm: 12 -36 hours typically depending on time of intercourse and time of ovulation? Food cravings are later in pregnancy. Nausea morning sickness typically comes first. Food cravings is not a good predictor of prgnancy.
