This actually varies greatly by age, as older women have higher rates of miscarriage due to things like amniotic insufficiency, and genetic abnormalities which also cause predispose towards miscarriage
>an induced abortion ("chemical abortion") is identical, medically, to a spontaneous abortion ("miscarriage")
This is not medically correct, and it sounds like a political talking point.
Many spontaneous abortions fail to implant due to genetic abnormalities, and come out like a period. Minimal pain or impact. Similarly, genetic abnormalities can cause spontaneous abortions that happen early pregnancy in the first trimester, causing the fetus not to grow, and then to abort.
There are several different chemicals used for an induced, chemical abortion such as salt, Prostaglandin, Urea, as well as steroids like mifepristone [1], or Misoprostol[2]
Chemical abortions on the other hand can be much more catastrophic, and involve intense enough contractions to cause permanent damage to the uterus and vagina. As you can see from the safety data sheets, these are non-trivial risks associated with these.
As a pregnancy involves signficant hormone changes, a pre-implantation spontaneous abortion without implantation would not change estrogen levels significantly. A fully implanted pregnancy would change estrogen levels as the breasts increase in size and prepare for milk production. Some studies have shown 90% increases in breast cancer rates post-abortion, while others contend no change.
