Pregnancy before or after reapir of ASD

I currently have an ASD that I found during my last pregnancy. I found it because I had a stroke. A clot formed in my leg and went through my ASD to my eye and Brain. I am doing fine now and my baby was healthy. However I would like to have one more child and I also need to have the ASD repaired. I am 36 now and don't have a lot of time to wait to get pregnant. Any advice on how long after repair to wait to get pregnant. One MD said 6 months another said 2 years. Hard to know what to think,

They also said no problem if I want to have another baby first then repair I will just need blood thinners again, I have concerns about this as well..
