Types Of Miscarriage:
There were many reasons for miscarriage, and they are classified into early and late miscarriages.
Recurrent early miscarriages: They occur within the first trimester, which is mostly caused due to genetic or chromosomal problems. Experts say that structural issues associated with the uterus might also play a part in early miscarriages.
Recurrent late miscarriage: They might be a result of uterine abnormalities, autoimmune disorders, a disorganized cervix, or premature labor.
Causes Of Recurrent Miscarriages or Pregnancy Loss
Many factors can contribute to recurrent miscarriage. Most pregnancy losses might be due to chromosomal abnormalities. However, doctors may not find out possible reasons always.

Genetic: Abnormalities of the embryo’s chromosomes is one most common cause of recurrent miscarriages, and 50-80% of miscarriages happen in the first trimester.
Uterine abnormalities: Around 15% of all recurrent miscarriages are caused due to structural problems of uterine. These uterus abnormalities are something like you’re born with, i.e., congenital abnormalities or birth defects such as the abnormally shaped uterus. Growth of Fibroids or polyps within the uterus in some women might show an effect on pregnancy.
Hormonal disorders: Endocrine abnormalities that warrant research include diseases associated with thyroid and pituitary glands, diabetic problems, or PCOS (polycystic ovarian syndrome).
Autoimmune diseases: Antiphospholipid syndrome (APS) is an autoimmune disorder that is defined by blood clots in the arteries or veins that can lead to multiple pregnancy losses or premature birth due to placental abnormalities.
Medical conditions: Medical conditions that are not treated like insulin resistance and hypothyroidism can increase the risk of pregnancy loss and poor obstetric outcomes.
Infections: It is believed that infections are unlikely to cause miscarriages and that too multiple pregnancy losses. However, some suspected infectious causes that lead to miscarriages are bacteria mycoplasma, ureaplasma, and Chlamydia.
Cervical weakness: If you are having a history of late miscarriages, then you may be at risk of cervical weakness, also called cervical incompetence. You may need to undergo scanning from 14 weeks to evaluate your cervix length. Depending on your test and pregnancy, you might be recommended to have a cervical stitch before pregnancy or during pregnancy.
