Changes in The Mother:-

1. Nausea and Fatigue:- Up to 80% of pregnant women have nausea in their first trimester. It is also called morning sickness as it occurs mainly in the morning when you wake up. It occurs due to the hormonal changes in your body. It causes vomiting, tiredness, and vomiting sensation. It ranges from mild to severe. If you have severe nausea talk to your doctor as it can affect the amount of nutrition your baby is getting in your womb.  Since your body is going through so many hormonal changes for the development of your baby, you may experience stress, mood swings, vomiting, and tiredness. You need some rest and proper sleep at this time. Eating healthy and nutritious food can make you stay active and healthy. Include so many iron-rich foods in your diet to prevent anemia which can make you more tired and your baby may also suffer due to a lack of blood in your body.
2. Food Cravings:- More than 70% of women have food cravings throughout their pregnancy and it is at a high peak in the first trimester. Some women may want to eat what they didn’t like before. You may feel hungry often and grab something or the other food item present in your kitchen. It can be from leftover rice, peanuts, Roasted channa dal, pickles, and sugar to junk food like pizza, burgers, donuts, and french fries. Many women feel hungry at midnight as the changes of hormones are at their peak levels during the night when they are asleep. Try to have a healthy snack every time you feel hungry.
3. Frequent Urination:- Since your uterus is growing in size, it puts pressure on your bladder which causes frequent urination as there is very little space for the storage of urine in the bladder. Don’t hold it or stop drinking more fluids. Urination passes out many harmful substances from your body and drinking more fluids at this time of pregnancy is very necessary for e healthy development of your baby.





4. Breast Tenderness:-  Your breasts may become sore due to the hormones which are preparing your breast to make milk for the baby who is going to come out in a few months. To feel comfortable you can wear a support bra or increase your bra size a bit. Your breasts may slowly increase in size throughout pregnancy as it is making milk. Your bra size may increase from 34 to 38 or 40. Your breasts will come back to their normal size after you stop nursing your baby.
5. Constipation:- This is very common throughout pregnancy and also after the birth of your baby. The pregnancy hormone progesterone slows down the digestive system of the body. As the digestion process is slow you may experience heartburn sometimes. Drink more fluids and eat fiber-rich foods to prevent it. Do some activity or exercise a bit every day. Eat small frequent meals. Don’t sleep after having meals. Avoid spicy, acidic, and citrus foods.
6. Bleeding:- Some women may experience slight bleeding or spotting in the initial days after fertilization occurs. This is also called implantation bleeding. Slight bleeding will cause no problems in your pregnancy. If you have heavy bleeding, cramps, and sharp pain you should call your doctor immediately as this can be a sign of miscarriage or an ectopic pregnancy.
7. Discharge:- A small amount of white milky discharge is common during the first trimester and also throughout the pregnancy. If your discharge is heavy every day you may need a doctor’s advice. If your discharge is green or yellow or smells very bad, it may be due to infection. So consult your doctor immediately.
8. Weight Gain:- At the time of pregnancy a minimal weight gain is considered as the healthy development of both the mother and the baby. But you should not become overweight. During the first 3 months, you have to increase from 3 to 6 pounds more than your normal regular weight. It is a myth that you have to eat for two. One for you and one for the baby. This is wrong. It can make you overweight and obese. You just need 150 calories extra in the first trimester.  Have a healthy diet for the healthy development of your baby.
