6 failed pregnancies

I have had two ectopics. My right Fallopian tube has been removed because the last ectopic caused it to rupture. Since then I’ve had four miscarriages in a row. I feel like losing complete hope. “God has a plan”, seems like all I’m hearing from everyone. Which I know is true but in times like this it doesn’t feel like it. I don’t have any problem getting a pregnant it’s staying pregnant that’s my problem. I have been seeing a specialist and we have tried low dose aspirin and progesterone inserts, that didn’t work. I’ve had blood work done and nothing is alarming the doctor. In December we started fertility treatments and during that time she said my uterus lining wasn’t as thick enough which is why she put me on a patch and progesterone. -that didn’t work. Does anyone have any advice? Anything that you tried differently that actually worked out to be a viable pregnancy. I’m at a loss of words and I don’t know what to do, think, or say. This hurts beyond belief because as a little girl I always wanted my own family!
