My brother and his partner found out at 20 weeks. She had very irregular cycles so it wasn't uncommon to skip periods but thought after 4 months without one she should do a test and ta-daa. They were both workaholics and kids weren't on the cards, not to mention the fact my brother thought he was shooting blanks. At the scan they were told they had 2 days to make a decision to terminate or not before it was to late, needless to say I now have a very adorable 8.5 month old niece
