Cant get pregnant

I was able to get pregnant 3 times on my own which all ended in miscarriage.. I have not been able to get pregnant again since July 2018... we have seen 2 different specialists and they cannot find anything wrong with me.. I am currently at the end of my cycle of clomid.. I dont test until Thursday... but I am sure aunt flo is on her way. I feel exactly like I do when I'm about to start... my boobs are not as sore.. and I just feel blah :( idk what to do...its so heartbreaking.. I don't understand how it was possible before but now with help nothing is happening at all 🤷‍♀️ I am 30 years old.. having a baby has been something I've always wanted.. I'm trying to come to terms with the fact I may never be a mother.. IVF is too expensive.. I mean on top of all my other debts with cars and student loans and all the other bills. It just sucks that something that I thought would be so easy has turned out to be the hardest thing I've ever tried to do. I've got some friends who were going thru the same as me but have since had their babies and havent been much support since because they "feel like they dont know what to say since I have my baby now" 😒 that's why I'm here. I need some supportive words... any motivational words to keep me going. My heart is broken.. and it's annoying. My husband doesnt even understand it. He doesnt care either way. Hes got his son. And yes he is my son too.. but I'm not the first person he thinks about on mothers day.. we have a bond..but it's not the same as he has with his mom.. so I hate when people tell me "atleast you have your husbands son" or "stop trying and itll happen" "plan a trip and itll happen" "you're lucky you are just an aunt and step mom.. the kids all go home" "here babysit my kid since you want one so bad"

It's nice some people dont struggle.. but they do not understand one bit what goes thru my head on the daily... I have tried so hard to not be jealous of others when they announce their pregnancy.. somedays are better than others.. I have NOT skipped out on baby showers because I know when and if it ever happens to me that I will want each of them there for me too. But even those can be emotionally draining when I get backhome....
