Decisions!

I have PCOS and my husband and I have been trying for 2 years to have another baby , but with my weight I have been talking to my husband about having the Bariatric Surgery , and with my husbands support and several others I have decided to go thru with it. I'm excited and scared but I know in the long run it will be worth it! But the doctor told me that we have to stop trying for a baby and I will have to go back on birth control, And we won't be able to start trying again for 2 years by that time I will be almost 40 yrs old! I'm just wondering if I have made the right decision?
