First-trimester abortions can have several causes. It is also possible to differentiate them into types of abortions, according to the development of the embryo and/or its place of implantation.
Some of the possible types of miscarriages are the following:
- Biochemical pregnancy: this is when the pregnancy test is positive, but after a few days the amount of beta hCG begins to decrease.
- Anembryonic pregnancy: an embryonic sac is observed, but without an embryo inside.
- Molar pregnancy: it is not an anembryonic pregnancy.
- Ectopic pregnancy: if the embryo implants outside the uterus.
In addition, any pregnancy loss before the 20th week is considered a miscarriage.
