So sounds like that you are doing a natural cycle IVF, thus what they are prescribing is a standard protocol. in case of fresh ET, they'd prescribe progesteron suppositories to supplement naturally produced progesteron by the corpus luteum. In frozen ET they prescribe more potent progesteron in oil shots. IVF clinics don't care about short luteal phases (and my RE does not believe in luteal phase defect) since they are attempting to circumvent this with progesteron supplementation.

They had me taking Progesterone, Estradiol, (both after retrieval) and baby aspirin (since cycle day 1) FYI.

Short luteal phase is an effect, not the cause of infertility. That’s what my RE said.

I’ll go in for bloodwork to catch ovulation and then either 2 days or 5 days after depending on which of my embryos I use. I do seem to ovulate on day 14. I tracked the last two cycles and I got a positive OPK on day 12 both times.

Probably suppositories.
