RU-486 cannot be used for abortions... You said it yourself... Many researchers have the drug and use it on animals for whatever reason, but it is not approved for the use in humans...
I cannot begin to fathom what havoc Depo shots could do to a woman's reproductive tract...
But hey, some women like to get busy and not suffer having unwanted pregnancies... So hey, all I got to say is protect yourself at ALL times...
My concern is with Sexual Transmitted Infections like HIV...
I nearly got cursed out asking how a woman who found out she had HIV because her first child was born with AIDS--but on her second child's birth, the child was HIV-free because the mother took AIDS antivirals during her pregnancy... I was like, WTF, HOLD UP--HOW IS SHE GETTING PREGNANT THE 2ND TIME??? And she cain't affort any Artificial Insemination or SIF??? And the MD researchers were like, we have NO idea what AIDS antiviral cocktails do to the unborn fetus...
Oh well...
