hiya my little sister is 16 and shes only just found out shes pregnant she also was on the pill i guess she was one of the unlucky ones. she hasnt had a period since the end of april and doesnt know how far gone she is as she doesnt think she is that far gone. she took a test last week and got 2 clear lines then took a clear blue digital which showed up not pregnant?? she took a first response the morning after it came up 2 lines but it was fainter than the 1 she took the day before does any1 know why?? she only took a test because she started feeling sick when she ate and has a bad back. she is petrified of telling mum so any ideas of how to be able to tell her?
