Hi, my girlfriend is putting off taking a pregnancy test but I'm desperate to know - she's 27 years old, has had one child and has always had her period on time (pretty much every 28 days like clockwork) apart from once when she was 14 days late. We decided to try to conceive in the middle of June and she was due her period 2 weeks later. It didn't arrive and she is now 31 days late. She's struggling to face up to it and thus won't take the test yet but how likely do people think it is that she's pregnant, is it very likely?
