I seriously know the feeling! We have been TTC with medical assistance for almost 4 years now and did natural planning for almost 2 years. We did an IVF cycle that did not work and have done 4 IUI's in which I got pregnant twice but MC both times at around 7 and 9 weeks.
January 2011 we decided to take a break for at least 6 months. In July we started treatments again and something was just not right. We immediately started second guessing our options. The break was so nice of fun passionate sex... no meds.. no tests... We started going out more...I could actually drink a glass of wine

During Thanksgiving we sat down and calculated how much we had spent on fertility in the last 4 years... the amount.... $45,000... that is more than enough for a nice car.. or two LOL.... I cannot believe we blew that much on treatments that did not work.
So we starting thinking about realistic options and ADOPTION came up. It was something we had talked about 3 years ago but I was TOO afraid to try it. So we interviewed 10 agencies in our area and found our fit. Submitted the application, got approved, and have our first meeting to set dates for home-study training and such next week. HONESTLY, this option will get us a child for sure. No more second guessing our options or if I am ovulating etc. There will still be the wait but in the mean time we can continue our lives and if we do get pregnant naturally then so be it.
The entire adoption will cost roughly $5000 but the military reimburses $2000 or up to $5000 if a sibling group like twins are adopted. With our open option of sex, race, and location we have been told the wait should be no more than 12 months. Which with our TTC track record that is fast! LOL Also, we have chosen to do foster adoption and not go the route of a birth mother just yet. That route was looking at around $30,000 and we thought heck no. If we are going to fork that out we will just do another IVF. Foster adoption does not always yield an infant adoption but will be looking at an age range or infant to 2 years of age. Also we have added the option of sibling groups with both no more than 2 years of age. There was a group to come through last week that was 2 months and 13 months.. perfect age range for us we are hoping we can push our training through to get the brother and sister

Our caseworker and lawyer are working hand in hand to help push the process through faster
I do not know if I helped any but wanted to let you know that you are not alone. Heading into 30 with 6 years of TTC behind us already.. we decided enough was enough for us. I do not want to end up paying $100,000 just to try to have a baby and then still have the years of expense ahead of us. We want to still be young and have fun. Travel is a huge thing for us and with all the treatments we have been doing it has not always been the right time or financially something we could do both of at one time.
