Hi moms, 
I'm 24 year old. I'm concerned about becoming pregnant due to my health issues. I have talk to my doctor and they have advised me to be careful when I do decided to have a child. My issue with pregnancy is that this would be a high risk due to my weight plus over my heart condition. How did you guys overcome all of this and still manage to have a healthy child birth. Or did u guys go with a surrogate.
