Rowing how you doing, honey? 
Scrummy big hugs to you. 
TigerseyeMum you are not barging in at all. You are most welcome. I agree totally with Keziah after 35 or 36 try for six months only and yes, get on the case and do not try without help any longer. If I were you I would go back to the endo clinic and start the ball rolling, ask what they can do and at the same time investigate NHS fertility treatment. 38 is young to me (I am 46!!!!) but actually or trying to conceive you maybe need to think about being more proactive. If sex is difficult due to pain (that was what I inferred from you post please correct me if I am wrong) I would find out how you can make it less painful and I would also investigate how you can try more precisely around the correct time. I have no idea what either clinic will suggest but I would get all the best advice you can and I would try and make a concerted effort to get the ball rolling. Also, I wonder if you maybe need to get your head around it a bit. You say your partner is more keen than you. Is there something holding you back, fear of something or anything else (money worries, medical stuff, issues?). If there are I would certainly try and address the concerns. I think although you are the right side of 40 you do need to take this seriously if you would like a baby, some people seem to get pregnant quickly but I know endometriosis can cause problems with conception (not for all) so I would just try and calmly find out all your options and also give some thought into what it is you are working towards, and rolling that ball at! I can honestly say becoming a mum is wonderful and I hope you will find out what you really want and the very best way to get to it. 
Ohh err Keziah I like the sound of CHEAPER and good fats etc, not a blood product. So I need to ask Dr about IVIG for raised NK cells or TH1 cytkotine levels raised - stops body rejecting the embryo, may need 3 in total at about £285 each. Thanks that is great. 
joycep hi and welcome, you are not barging at all either. Sorry I can?t help, I am not sure exactly what to recommend but I would investigate which immunology testing you can get on the NHS and get anything you can done for free (which is non-invasive and helpful) done. My tests showed a thyroid problem. Which I now take tablets for. Good luck. 
Lucy I am going to ask about humira to bring the raised immunes down, if I do have raised immunes. 
Hugs to all, love and baby dust and chocolate boobs!

Can I ask how many of you conceived naturally before IVF and how many of you conceived naturally after IVF (or after other treatment). I wonder if we have a smattering of both. I have never known this activity on the thread!
