Need help 4mc and 4 laps for endo so discouraged

Meggen

So my husband and I have been together going on 12yrs and in that time we've had 4mc and I've also have had 4 laperscopys for stage 4 endo and also have been put on Clomid to try and get pregnant immediately after my lap. And it cause bigger then golf ball sized cyst on both ovaries and also had to have another lap after that because it caused my endo to grow fast within months apart from laps my dr. Was shocked when he found that I was stage 4 again in just such a short time now I'm seeing a fertility dr which they want me to start letrozole on 3rd of period which I have been trying to do for 3months but they found another cyst and now I'm getting discouraged is there any advice from some of you that have had some of same problems looking for any kind of help!!!!
