Feeling amazed

First of all let me say that if this offends or hurts anyone I'm sorry. That's not my attempt. My husband and I are both 43 (well I will be next month) and we both have 3 kids of our own. So yes together that makes 6. I have always wanted 6 kids. This may sound mean but I'm not really close with his kids so I don't feel like their mine. We have been ttc for almost 3 years. We had a miscarriage in Nov of 2014. We just started all the tests for IVF in Dec. Found out I have low egg reserve. I have wanted this for so long and so bad. I had finally given up all hope and was preparing for a huge depression when things turned and we were able to pay for IVF. The insurance won't cover it. I know I'm running out of time and this is probly my only shot. We got 9 eggs on Friday and 5 fertilized and are doing great. Tomorrow morning we are transferring 3-4 embryos! I can't believe it. By 10am I will be pregnant! Something I thought was not meant to be. I am hoping and praying it all goes well and they stick. It's been 12 years since I have been pregnant, besides the miscarriage. I feel really confident about this one. I know for most of you in here it is your first and there will be some resentment towards me cause I already have kids. But I have wanted this for longer then you know. I wish all of you the very best of luck and may you have lots of beautiful babies. Sorry I just had to tell someone who would understand.
