Would a 25mlu preg test show a positive 3 days before AF due?

I have just been talking to my SIL on the other side of the world and she has been having fertility treatment. This is the first cycle that she may be pregnant. AF is due in 3 days and she can only get a 25mlu test. Would a 25mlu show a positive 3 days before AF is due. I have my fingers crossed for her. She so desperately wants a positive.

not sure that it would show,maybe with FMU hard to say. Sometimes they are only good on the day AF is due , but everyone is different, fingers crossed for her.
