Short luteal phase and (mostly) unmedicated FET...

[Anonymous]

I’m supposed to be going forward with an unmedicated FET next month. My period seems to be starting (I started spotting brown today so day 1 likely tomorrow) which will have made my past cycle’s luteal phase 9-10 days. My clinic will have me begin progesterone after the transfer but the cycle will otherwise be unmedicated. Cause for concern or not really? I emailed my nurse but won’t hear back until Monday. TIA!

What kind of progesterone are they giving you?

what day of your cycle is the transfer?

Probably suppositories.

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.

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.

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.
