Endo-Freak Please do not give up. Let me give you my story, hopefully in shortened form.
I started ttc about 8 years ago. It wasn't working, which didn't surprise me as my sister had problems. so I spoke with my obgyn and he put me on chlomid. After 3 months of that, I felt horrible. I had a terrible throbbing pain in my right ovary. I could hardly walk. When I spoke with dr. he said it was my imagination and to just take some pain meds. I did this for a few weeks, then went in for my annual. Well, sure enough I had a cyst the size of a softball on my ovary. He just said lets keep an eye on it and see what happens. Welll, within a week it had ruptured along with my right tube. I was devistated, but relieved at the same time. I was relieved because I was finally diagnosed with what they thought to be endo. (I had always had the most horrible periods, but just figured it was normal). So I researched succesful dr. and ended up going to Oregon to see Dr. David Redwine. (I used him because we thought the endo was on my lungs, and he is 1 of 10 in the world who deals with this.)
Anyhow, he said it was the worst case of endo that he had seen in his 20 years of practice, but that he got it all.
One year later I still was not pregnant. So, I sought out a good endocrinologist and he discovered that my remaining tube was blocked and due to tons of scar tissue he thought I just needed to remove it and do IVF.
I said NO WAY!!!
However, a few months later my sil told me that if 10 years down the line I thought I would regret it, then I better go ahead have the tube removed and start IVF. I made the call that day.
Anyhow...did IVF once and got a BFP

I have a beautiful daughter who is 3 years old now.
We were able to pay that very expensive cycle because we had just sold our house and made a profit.
However, last year I underwent IVf again. Unfortuantly the endo had removed which was not good. So, Sadly I got a BFN
I was gutted as this was $15000 that could have gone towards my dd college education...and to make matters worse, we didn't have the money to pay for it.
I have worked a deal with the clinic where I just pay them $100 a month and we are good. So, it will take FOREVER to pay off this BFN, but at least it didn't strap us terribly.
We just underwent a FET, and we are hoping to be pregnant now. WE will find out in about a week and a half.
My main thing is don't give up hope. Talk with the clinic and see if they will work with you. Age is a factor when it comes to IVF. I don't always think that our dh understand exactly what we are going through in all this.
Please feel free to pm me if you want to talk.
good luck with your tough decision
