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.
Actually the third trimester begins at 28 weeks. It does not really matter what you call it. But I go with 27 weeks because in reality you are pregnant for 3 equal periods of 13 and a 1/3 weeks (or 13 weeks plus 2+ days). That math will give you 40 weeks. So really at 26 and 2/3 weeks (or 26 weeks and 4/5 days) you are 2/3 of the way done.
