Los Angeles: TV presenter Alex Jones is worried she won't be able to have children. Jones says she has undergone an ultrasound and a blood test as part of her new show “The Truth About Fertility”, because she's concerned she only has a small window to get pregnant after her mother went through early menopause. “It's useful to know because we shouldn't hang about, but at the end of the day, what can you do? You hope it will happen. It might, it might not,” Jones told mirror.co.uk. “The more pressure you put on yourself, the worse it becomes, because the one thing you want gets further out of reach. I haven't chosen to leave it until I'm 39 - that is the situation I have found myself in,” she added.
