TTC but 6 day luteal phase

Hi all,

I have a 2 year old conceived after a MMC, both times I got pregnant previously, I conceived on month 2 of trying. I use natural cycles snd could see my luteal phase was short - 11-12 days, however, we’ve now done 3 months trying for baby number 2 and the two months I’ve tracked properly show ovulation on day 18/19 and a 6 day luteal phase! On googling it, this sounds ridiculously short and I guess not enough time to allow for implantation.

I’m so lucky to have one child already, but we had our hearts set on two with a 2-3 year age gap… this is now slipping away and with the luteal phase situation, I’m concerned we won’t be able to conceive again at all - please can you advise if you’ve had this or know if there’s a way of extending it? I have a drs appt booked at the end of the month but I’m not sure what to ask for, or how much the NHS can do?

Straight to a private doctor and get progesterone.

Don’t waste time fannying about trying to get an NHS GP to sort it.

Cost me £125 for the appointment, then I was pregnant literally the first month. I wasted a year before that.

There's evidence that vitamin B6 can prolong the luteal phase.

How are you tracking your ovulation?

@howaboutapuffin oh really! When I’ve googled it, it seems to say no evidence shows progesterone works, good to hear you’ve had success with this!

@redcords26 I’m using natural cycles temp tracking, and LH testing - I seem to be ovulating on CD18/19 - my overall cycle length is the same 26 days as usual but ovulation later

I used it for 2 of my 3 children. Short luteal phases are literally caused by the progesterone in your body falling too quickly …

Now I would always advise it if you’re confident you do have a short luteal phase and your measurement is accurate. Mine is 9 days without ‘help’ from progesterone.

Good luck!

@howaboutapuffin thanks! Did you go to a fertility clinic?

I found a private gynocologist (one recommended on mumsnet, actually!), she had a scanner in her office. Good luck!

Mumsnet was more useful to me than any fertility clinic or GP 🙈 I learned about short luteal phases on here, it matched with my tracking and I was able to solve the problem quickly, simply and inexpensively!
