Investment is the commitment of money or capital to purchase financial instruments or other assets in order to gain profitable returns in the form of interest, income, or appreciation of the value of the instrument.
Another common term you'll hear throughout your pregnancy is trimester. A pregnancy is divided into trimesters: the first trimester is from week 1 to the end of week 12. the second trimester is from week 13 to the end of week 26. the third trimester is from week 27 to the end of the pregnancy.
As such the second trimester will begin as week fourteen and the third trimester will begin at week twenty seven. You can decide which due date calculator and trimester calculation method you would prefer. Your doctor will help you out with this, or there are also various books that also offer advice.
