First Meck, I am so sorry that you and hubbs are going through such a difficult journey. Welcome to the IF board, there are many fab ladies here that have been AMAZING through my journey.
Warning and disclaimer since you asked specifically my opinion about faith I will give it.
Back history, we suffer from male factor infertility also. Severe across the board everything was off. We were told our only option was IVF with ICSI. We did 2 rounds already one was a bfn, the 2nd I made it to 5w4d pregnant then miscarried. I am about to go into cycle 3. I say this to bring me to my point.If it was not for my faith I would have been completely lost. I am a born again Christian, accepted Christ, and even work in a outreach ministry.*sign language, I interpret service. :) My mom was raised Catholic so I chose to go with a relationship vs religion.She has since joined my church and is born again also.
I will admit I side eyed God like really, a m/c like I have not been through enough. I had a aha moment though if he brought me to it, he would bring me through it, and it strengthened me more than ever.Maybe someone might need my testimony one day, I am one of those people that believe God's will for me. It is so hard to trust in something to the point of saying your will be done, but really meaning it. As a Christian you will know or learn the story of Job, he went through HELL, lost everything, but it was all a test, only the strongest I believe are picked to go through such tests as IF. Again, I know what a touchy subject of God's will, but I believe everyone is meant for a different path to parenthood, either adoption, surrogacy,all roads lead to rome, and I believe everyone should get to experience it. I have been through many many fires, so that is why I believe the way I do.
I let go this past cycle, and I believed that if I was meant to be pregnant it would happen for me somehow, and I prayed for signs, should I just move on, and then I got a call from Re yesterday saying how close we were, and how she really felt this next time was it. All roads led to biochemical, husband fertilizing all embies almost etc.Just when I was getting ok with this all not working and maybe not ever having kids, I get this sign of hope. not to give up.
I say this because I feel less loss, I am not sure why I had to go on this journey, I have made some amazing in real life friends, it has strengthened my faith, relationships etc. I will be blessed either way I believe that, and I actually believe either through pregnancy,adoption whatever that I will be a parent. That is the peace I have in my heart because I leaned into God for his strength not my understanding. I stand here today after just going through a miscarriage a week before christmas stronger than ever with a determination, I know that didn't come from me, I would still be in bed sobbing and grieving a loss.
All that being said, there is nothing wrong with being plugged into your church, or a source of faith that you feel comfortable with. Eat the meat, spit out the bones so to speak. You do what makes you comfortable, the road ahead of you will not be easy, but it is VERY possible. For all you know a simple treatment or surgery will resolve hubbs IF. I pray nothing but the best for you, many woman have endured it and been successful, stay encouraged and if you ever want to talk further, please feel free to pm me! I am excited for you!!!!!!!! (((((hugs)))))) <3
