Derailment (thought disorder) In psychiatry, derailment (also loosening of association, asyndesis, asyndetic thinking, knight's move thinking, or entgleisen) is a thought disorder characterized by discourse consisting of a sequence of unrelated or only remotely related ideas. The frame of reference often changes from one sentence to the next.
But remember -- you want to be sure you deliver a full term baby if possible. Pregnancy lasts for about 280 days or 40 weeks. A preterm or premature baby is delivered before 37 weeks of your pregnancy. 1  Extremely preterm infants are born 23 through 28 weeks.  Moderately preterm infants are born between 29 and 33 weeks.
You can do a pregnancy test from the first day of your missed period. If you have regular periods, youâll probably know when this is. If youâre not sure when your next period is due, you can do a pregnancy test 21 days (three weeks) after you last had unprotected sex.
