Answer :
During pregnancy, most women should gain between 25 and 35 pounds (11.5 to 16 kilograms). During the first trimester, most women gain 2 to 4 pounds (1 to 2 kilograms), then 1 pound (0.5 kilogram) per week for the rest of the pregnancy.
You may miss or be late with your period around 4 weeks of pregnancy, which is also 4 weeks from the first day of your last period. This is frequently the first and most noticeable symptom of pregnancy.
An at-home test may yield a positive result as early as 10 days after conception in many cases. Wait until after you've missed your period to take a test for a more accurate result. Remember that if you take a pregnancy test too soon, it may come back negative even if you are pregnant.
Pregnancy is divided into three trimesters, each lasting about three months. Conception occurs during the first trimester, when the sperm fertilizes the egg. The fertilized egg then descends the Fallopian tube and attaches to the uterine wall, where it begins to form the embryo and placenta. Miscarriage (natural death of an embryo or fetus) is most likely during the first trimester. Movement of the fetus may be felt around the middle of the second trimester. If given high-quality medical care at 28 weeks, more than 90% of babies can survive outside the uterus; however, babies born at this time are more likely to suffer from serious health complications such as heart and respiratory problems, as well as long-term intellectual and developmental disabilities.
