OPC has always been more conservative (as is UPC and EPC). It’s the PCUSA that is mainline....and fallen away.
That issue can’t be solved - an unborn child is both - a human beeing and a part of it’s mother. So it has a right to live and the mother has a right to have it removed.
As it concernes nature the consciousness sets in even AFTER birth so that can’t be a criteria. Ca. 44 to 48 days after ovulation nerves begin to interconnect - so somewhere there will be the point where sensing starts.
Drawing a line here would be appropriate.
