First trimester: early changes occur such as missing your menstrual cycle, ovulation increases, etc. you may experience mood swings, fatigue, headaches, morning sickness, etc. this is when hormonal changes affect almost every organ in the body. the baby’s heart begins to form, it is now considered an embryo.
second trimester- all those symptoms i mentioned in the first trimester start to fade. baby bump however starts to show, you may even feel the baby move. the second trimester is the most painful trimester since the baby is really really starting to develop. you may experience back pain, numbing, groin pain, etc. the baby is now about four to five inches long and weighs about three ounces. like i said before, the baby can start kicking due to the fact it is now more active than before in the first trimester.
third trimester- the lasttttt trimester yayyy!! many contractions occur, some swelling may be present. movements and kicking increase, the baby’s eyes can open and close, breathing practices and movement occur. the baby is now at about 16-19 inches long and ways around six pounds. the baby’s organs are now capable of functioning on their own!’
