Hi All!

My sis sent me a message today that her DH talked her in to doing a HPT because her AF still hadn't shown up since coming off the pill roughly a month ago. And well it turned out to be negative.

I remember back in our teens that my sis got her AF very late because she was quite athletic and was in to a lot of different sports. She went on the pill to regulate her cycles.

Since then she's been on the pill, mirena and then back on the pill for about a year.

I seen my sis today after about 3 weeks and she is looking very slim and very lean so must be on a pretty strict diet with the gym training she is doing. So could the cause of no AF be that her body fat as reached a low level that will stop AF showing up?

My sis said that she will wait 2 more weeks before going to see a doctor but is googling for some answers for now.

Any opinions/advice would be greatly appreciated!!

TIA
