So, as titled, I didn't think I'd ever have any more children, we have 2 already. After a unplanned miscarriage a few year ago, and suspected chemical this year, we have decided to try for another baby. However my sister In law is trying to concieve and has been for 1 year. I know I should put my own happiness before anyone else but I can't help but feel a sense of guilt for deciding to try incase we fall before them. Any opinions would be greatly appreciated
