Answer :
Systemic disorders such diabetes mellitus, chronic renal disease, and lupus are linked to early pregnancy loss and are the leading causes of first-trimester pregnancy loss. Chromosomal abnormalities are the most typical cause of spontaneous pregnancy loss in the first trimester.
The term "pregnancy loss" refers to the loss of a fetus at any point in the pregnancy. First trimester, second trimester, and third trimester are the three stages that make up a pregnancy.
A full-term pregnancy lasts about 40 weeks starting on the first day of a woman's last period, while a trimester lasts between 12 and 14 weeks. A miscarriage that occurs between 14 and 24 weeks of pregnancy is referred to as a late miscarriage, sometimes known as a second-trimester or mid-trimester loss.
It is typically thought of as a missing or silent first-trimester loss if a baby passes away before 14 weeks but the miscarriage really occurs later.
