Dh's cousin is pg with her 3rd baby. Actually this is her 5th pregnancy.
Whenever she has fallen pregnant it has always been "by accident". Now, she had her first baby at fifteen so I can quite believe that the first one was unplanned, or that she hadn't been taking her contraception properly and had ended up pregnant. She had another baby at eighteen again due to "contraceptive failure" and she is now 23 and pregnant again, again due to "contraceptive failure".
In fact, she had two miscarriages last year and is now pregnant again, all of them were down to "contraceptive failure".
I don't care if she wants three children - that's up to her. But I can't see why she can't just come out and say that (esp this baby, as she is now in a long-term relationship) was planned and why she feels the need to make up a story about contraceptive failure.
Of course contraceptives can fail. But five times? I think not.
