[|AI|]  Hello, Thanks for your query. Home pregnancy tests read well when performed 3-7 days after a missed period with a fresh early morning sample of urine. Since your wife has her periods with a span of 4 days every time, she should wait for at least 3 days after the farthest expected day to perform the pregnancy test. That is to say, she needs to wait until the 5th of the month. If you wish for an earlier clarification, you can get the serum beta-ChatDoctor titles done. A trans-vaginal sonogram performed about ten days after the expected period also helps to confirm/exclude pregnancy. Hope this helps.
