Hi everyone, I’m feeling a bit anxious and could use some advice. Recently, I found out that I have a thin uterine lining, and I’ve heard conflicting information about whether this puts me at a higher risk for pregnancy complications. I’m eager to hear from anyone who has been in a similar situation or has knowledge about this. Any insights or personal experiences shared would be greatly appreciated. Thank you in advance for your help!
Have you joined the Facebook group for support with thin endometrium? It has been a helpful resource and has given me hope. We transferred a 4bb+ euploid embryo on my 5.5 lining 9 days ago and today my beta was 284! It may be early to celebrate, but I am grateful we went through with the transfer. You can find plenty of advice, information on successful protocols, and thin lining success stories in the group. The general consensus is that trilaminar appearance matters more than total thickness. In the group, there have been no reported issues with thin lining affecting pregnancy later on.
I have not come across any research regarding the impact of thin linings on later pregnancy complications. Once the embryo attaches, pregnancy hormones continue to support its growth regardless of the thickness of the lining. The lining is primarily important for successful implantation.
My initial transfer was 6MM, but after PIO, it decreased to 5.7 on transfer day. The pregnancy progressed normally, with induction at 40 weeks. Despite walking over 3 miles daily and working until induction day, everything went smoothly. Currently, my pregnancy is high-risk with a plushy lining.
I am consistently on the slimmer side as well. My reproductive endocrinologist is aiming for 8mm thickness. It was 8.1 in our previous attempt, but unfortunately, we miscarried and had to undergo a D&C. I have always believed that the thickness is critical at the beginning of pregnancy. If the embryo implants and grows, the hormones will balance out naturally. However, I have yet to receive any concrete information about this. I am currently undergoing acupuncture to improve my lining thickness for our final euploid embryo transfer. I am also hoping to avoid high doses of estrogen required to reach the 8mm goal.
I have never heard of that before. Some clinics may not prefer thin lining due to concerns about pregnancy rates, but I am not aware of the adverse outcomes you mentioned. My lining during a successful FET was less than 6mm, around 4.9mm. My clinic did not disclose the exact number, but assured me it looked perfect. They emphasized that the trilaminar appearance was more important than thickness. Despite my initial concerns, I had a healthy pregnancy with regular monitoring due to my high-risk history. The FET with thin lining resulted in a healthy pregnancy and baby, with a normal delivery.
Where did you come across that information? According to my understanding from listening to Fertility Docs Uncensored and As A Woman podcasts, the addition of progesterone causes the lining to automatically compact down and lose its trilaminar appearance. Therefore, I’m not certain how the thickness of the lining impacts the situation. Also, eventually the embryo will be floating in the gestational sac, followed by amniotic fluid.
I wanted to share the article I read titled “Obstetrical complications of thin endometrium in assisted reproductive technologies: a systematic review” and include the link for reference. Appreciate any feedback or responses.
Since you mentioned scarring and are not on Facebook, I suggest joining the Asherman’s Syndrome Support & Awareness group there. Many women with scarring struggle to build up their lining, but some have had success with linings of 6mm and under. I am also an Asherman’s patient and can relate to the challenges. Feel free to message me for support. Best wishes to you!
