Sarah wrote in to Ask The Egg Whisperer, and she sent the following question, "I have done 12 embryo transfers over the past 2 years (failed due to several reasons). During the transfers, my lining always thickened nicely (minimum 9), I have never had a problem with thin lining. All my cycles were medicated and not natural FETs. However, for the past 2 cycles, my lining has been thin (doesn't exceed 5). What could be the reason?"

Uterine lining, and a thin lining can definitely be an issue. In cases like this, I encourage people to ask for the official report from the hysteroscopy procedure and see if they might have done something called a DNC at the same time. They may have also done some sort of biopsy. An endometrial biopsy has a 1- 2% chance of causing uterine issues.

So in a case like this, I would consider doing a saline sonogram to see what's going on. Look for a ban of scar tissue, and consider estrogen injections to thicken up your lining.

Ask for the reports because something's not adding up. It's really hard to imagine that you would go from 9 all the way down to 5 without anything causing it. Other possibilities are a low lying infection, scar tissue from the hysteroscopy, or body size change.

There's so many different strategies and ways to improve your lining if you're dealing with a thin lining. You've been through so much with your 12 embryo transfers. I wish you all the best, and I hope that your next transfer works.
