The Bloom cervical ring seems like a great idea at first glance. It's a high-tech device, which automatically measures the BBT ( basal body temperature) of the women, so she can track her BBT chart automatically, and thus pinpoint her peak fertility.
It's being sold as a clever, inexpensive device, to " pinpoint the window of fertility".

Sadly, what the manufacturers have failed to realise is that BBT charting is not useful for infertile women who are trying to get pregnant. The BBT rises only after ovulation - and by this time, even though the egg is still alive, the cervical mucus has dried up and will not allow the sperm to pass through, which means the woman is no longer fertile !
