“Oral contraceptives are not abortifacients. The corpus luteum produces higher levels of hormones than the levels achieved from OCPs.”
I believe you are incorrect here. The zygote cannot implant because the Pill renders the endometrium unfavorable to implantation. Therefore, the early baby is aborted.
No, this is a very old idea that’s not supported any longer.
The American Association of Pro-Life Obstetricians and Gynecologists have reviewed this worry:
The uterine lining is affected much more by the hormones produced by the corpus luteum after ovulation. (probably influenced by what ever caused the breakthrough ovulation)
There is an increased risk of ectopic pregnancies if using the “mini pill.”
