Hi polo polo, understand how u feel. Most impt it's bb health. U can try 3rd one if financially manageable. I also have a son le. When my Gynae told me my no 2 may be a boy. I think I show my disappointed face out n my Gynae immediately console me telling me that bb is healthy n active n growing well. After he says these I never think much of the gender le. So I think wat most impt is bb health. Even though now I still got abit hope tat may be a gal. Hehe.
