TTC my 1st for 5 years😔 need to vent

I am 26 going on 27. I have been TTC my first for 5 years now. And only once i was pregnant. I had lost my baby 8-9 weeks because i had a tubal pregnancy. I lost my left tube as well. I had caught chlamydia from a guy when i was 18. I went to the Doctor soon as i heard about he might have it. I feel like giving up its been so long. Also i am married to a man that is older than i am. He will be 40 in a month or so. I don't think i will ever become pregnant. Especially with our age difference. He already has kids of his own from previous marriage. I love them but there not my own kids. And I could tell they dont have that bondness with me(their teenagers). They look at me like im the enemy. Â
