From what I read, in many places rights depend on viability. Unfortunately in Texas it depends on what is mistakenly thought to be a heartbeat.
Apparently it can also depend on the woman’s intent - whether or not she wants to carry to term.
I seldom get far into discussing this area because it seems to rapidlly degenerate into beliefs, which vary widely and are vehemently defended.
Not this thread, that’s just my past experience.
