A chemical pregnancy is simply a miscarriage that occurs very early on in a womanâs pregnancy. Often, this is because a woman was able to obtain a positive determination of pregnancy from a test before her period typically occurs.
As many as 75% of miscarriages occur in the first 3 weeks or so, before a woman even knows she is pregnant. As many as 25% of pregnancies end in miscarriage before 12 weeks, with the rate being slightly higher for women who are older.
