Tanny, I have what has been described as 'abnormally thin' lining, often getting only 2mm at day 21 since LMP. I have twice had to take oestrogen for recovery from gyne surgery on one occasion I got up to about 2 cm(!!!!) which was, to be fair, after a particularly complicated MC with multiple ERPCs. I don't think it usually thickens it up that much.
I asked Prof Regan about it and she didn't seem too worried in my case as I get to about 6-9 weeks so she didn't think it was an implantation issue. However, I have been having acupuncture for a few months and have had reflexology in the past. I also had a cranial osteopath manipulate my pelvis to try to get more blood flow to that area (I had a coccyx injury from years ago and apparently things were out of whack). Maybe those things help, maybe not.
I agree with Baking about the phenomena that 'scratching' the lining actually stimulates it (I am hoping my IUD removal will have had the same effect), but I expect that that puts you in a catch 22 situation as you might be wanting investigations, which you may have to wait for.
Of course, everyone's issues are different, but I reckon that if there are tablets/herbal remedies/certain foods that can help, then I say go for it.
Baking, I have decided (probably, inevitably, foolishly) to 'see what happens' for a couple of months and hold fire on going to Prof Q. She's next, if I'm still looking for answers in a few months. Thanks for the info. Hope I don't live to regret it...
Waves to all!
