Death is medically defined when the heart stops for a set period of time, biologically defined when the brain dies. Prior to 5-6 weeks of gestation a fetus has neither a heart or a brain. The neural tube is just closing at this point, and inside that neural tube the spine, and eventually, brain will form. .... .. if it can’t die medically or biologically- meets none of the criteria defined for life- how could it be “alive” or defined as a child prior to 5 weeks? Life does not begin at contraception.
My 2 cents.
