Ideal lining on or around CD10?

KelliLynee · November 2011

I go in tomorrow for CD10 testing. We are doing a monitored cycle and will TTC if my lining is looking good, but I have no idea what to expect and the nurse I think I am seeing is kind of vague.

For those who have had mid-cycle testing, can you share what I should be looking for/hoping for tomorrow?

Last month on CD21 (but possibly 3dpo) my lining was 5.76mm. I've been taking baby aspirin and drinking 8 oz pomegranate juice daily since CD2 this month and am hoping for some improvement.

Thanks for any and all feedback you can provide. Dr. Google was sort of a bust.

I don't know... having the same problem with the vauge nurse and all. Went yesterday at CD 17 and it was only at 6mm. I think she said it was supposed to be around 8, but not sure. She better get back to me soon as I am hoping to ovulate in the next day or two. And I agree Dr. Google is a bust on this subject.

Good Luck to you!

Here is a quote from an OB I found online and it fits with other things I remember reading. However, my RE told me that having a trilaminar lining is more important than the thickness. I don't know how quickly the lining grows though, so at CD10 I would think it would be still growing.

Medical studies have yet to define what the optimal thickness of the lining is for a successful pregnancy. In general, 8-13mm is good, less than six is potentially a problem, and greater than 14 could also reduce chances for pregnancy. Pregnancies, however, do occur when the thickness is less than 6mm, but not as often.

Oh, and please keep us posted on what the doc finds! My next cycle is going to be a monitored one, so I'm curious what will happen.

Will do! Thank you ladies. Does anyone else out there have anything to share? Has anyone been told what to expect on CD10? This appointment will be our deciding factor whether to TTC or TTA this cycle.

I have had mid-cycle monitoring the past four months. By CD9 or 10, my lining is usually 9mm. The nurse simply told me my lining looked good, but she never mentioned what was an acceptable range. The past four months I ovulated on CD11 (once), CD14 (twice) and CD15 (once). So, if you tend to ovulate later than that, maybe you don't need to worry as much about the CD10 number because your lining still has more time to grow??? Good luck.

Mine is typically at 9-10 and I've heard what Twizzle posted about 9-13 being "optimum" and 6 being less than ideal. Today at CD14 mine was at an 11, which again, is typical for me. I would think they would look at what is both typical for you and what is "optimum" and help you understand if there was any improvement. Remember too that in the event you don't have optimum thickness there is still time to try to improve it with endometrium/estrogen or viagra, if you wanted to.

Thanks ladies. I thought I remember learning in pharmacy school that estrogen is only given to improve lining when given with fertility drugs, which I am not currently on. Though it seems that isn't actually the case?

I usually ovulate between CD15 and 18 (at least in the few months I've been charting), so CD10 still seems early enough to make a difference.

How much has estrogen improved your lining? Did they have you go back in a few days later? I'm not sure what the plan is after tomorrow appointment, but I would love some 7dpo labs so maybe I can push for that.

Thank you!

My RE always told me that over an 8 is great, and they like at least over 7. However, he also said that a tri layer lining is more important than the actual thickness.

I'd ask the question about estrogen on PAIF and maybe SAIF. I don't know why you would withhold estrogen if not also on other fertility medications. Imagine a situation where thin lining was your only IF issue - seems to me that a doc would be a real peach to say well you could have this relatively cheap and easy fix but first we have to give you Clomid or Femara or injectables. I seem to recall at least one or two women on those boards having taken medications to increase lining during FET cycles where they aren't currently stimming. It's a thought anyway and I think worth asking your doctor about. As someone said the other day on TTCAL, there's no empirical evidence that POM actually works yet women do it all the time. On the other hand, there is some evidence that estrogen helps.
