recurrent miscarriages

hi, I have had 7 m/c's(one failed ivf). I have visited several RE's,got all lab tests and blood work done except the immune tests(like one for natural killer cells). Although one of them for antiphospholipid too has been done and that turned out to be positive. I have endometriosis but it has been cleared recently through laproscopy.I have tried progesterone supplements, heparin-aspirin injections but nothing worked. My each pregnancy follows a same pattern-implantation occurs without problem, hcg rises, but u/s detects no heartbeat and hcg begins to fall at 7th week. ultimately i end up getting a D& C done. Can anybody suggest me any possible treatment or just lemme know what could possibly be wrong? I have no uterine abnormalities,no signs of chromosomal abnormalities, my husband's lab work turns to be fine. I just want to know the path to move ahead.
Also if anybody knows someone or has read a case similar to me ,can you please give me the details. Your help would be greatly appreciated.

I don't really have a suggestion, but I wanted you to know that I am very sorry for your losses. After having 2 mcs myself, I know how painful they can be.

Have you sought the advice of another doctor or two? Maybe a new set of eyes will have a better perspective on what is going on?

You will be your own best advocate. No one else will be interested in your case unless you make them interested. You need to be assertive and demand every test possible to find your answers, even if that means repeating tests.

I wish you luck. Take care.
