My friend is pregnant and she said that she has a really short time from when she ovulates to when her period starts so three days before her period started she took three contraceptive pills to delay her period and continued to take them and then she found out she was pregnant on CD16? Is this actually possible if so how clever! Just want some opinions... don’t think I would do this myself though

EDIT:-

Ok so this didn’t sound too right and I didn’t think so! But she said she was tracking her ovulation and she said they had sex on her peak day or whatever but then three days after having sex she took the pill to stop her period to give her baby more time to implant? But it still doesn’t sound right does it!
