A 25-year-old female asked:

when do pregnancy symptoms start? also, if you're only about 2 or 3 weeks pregnant would that mess up the menstrual cycle that early?

As early as 1 week : I have heard patient describe symptoms as early as 1 week after conception (or 3 wks after first day of last period), which is about a week before pregnancy would be detectable by most urine pregnancy tests. Most women however describe onset of symptom starting 4-6 wks after the first day of their last period.
