What is the first trimester of pregnancy?
Pregnancy has three trimesters or stages. Each trimester is about 13 weeks or three months long. Pregnancy that is full-term lasts 40 weeks, or nine to ten months. Weeks will be used by your doctor to describe fetal development to you. The 13th week of pregnancy marks the end of your first trimester.
Despite what you may think, your pregnancy actually starts on the first day of your last period. This is called the gestational age of the pregnancy. Your due date is determined by a prenatal care professional by adding 40 weeks to the first day of your most recent period. This implies that by the time you become aware of your pregnancy, you are about four weeks along. This can be very confusing!.
Your normal menstrual cycle includes your period and ovulation in the first and second weeks of pregnancy, respectively. Your fallopian tube is where your egg travels to your uterus after you ovulate. If it comes into contact with sperm, they combine and get pregnant (fertilization).
Your uterus receives the fertilized egg during the third week of pregnancy. It divides into additional cells as it descends to your uterus. It enters your uterus and implants itself in the lining there. Your body then recognizes that you are pregnant as a result, and a number of changes take place. The majority of women who miss their period also test positive for pregnancy.
