I don't know how to continue anymore.

I'm definitely losing all hope. I wish I could be positive like I use to be. thankfully I had an hsg test done which showed my remaining tube was fine and I know people say it makes you more fertile but idk how much more fertile I can get with one tube when 98% of the time I ovulate from the side with no tube. I've ovulated twice from my right side in 2 years. which were my last 2 miscarriages. my 1st lost was ectopic on my left side.. my OB has possibly figured out why I've had the last 2 miscarriages and I've been on, I guess you can call it, vitamin therapy? I took my 6 weeks labs to see if it has helped any. 3 years of ttc I feel like I don't know what to do anymore. we've done the "don't try", preseed, I do opks, take my bbt. have tried having sex everyday, every other day, every two days. you name it. I tried the whole grape fruit juice thing to get more ewcm as well as mucinex. none of that has worked. I've tried "not stressing" but it's hard when I've lost 3 babies, 1 tube, have endometriosis, pcos, and hyperhomocysteinema (which is kind of similar to a clotting disorder). I just feel like it's not going to happen. since my remaining tube is fine my OB is going to have me take clomid so I can ovulate more on my right side but I still face the risk of miscarrying again. I just don't know how to continue going on. I don't know what to do anymore.
