How reliable are contraceptive devices like Ladycomp? I want to go on that method because it's all natural but I would like to know how effective that kind of method is.
Some trials have shown it is significantly more reliable than typical fertility awareness methods.
The makers indicate imperfect use is more effective than imperfect use of the pill.
Normally fertility awareness is usually not as reliable, due to the larger risk for error and the inability to perfectly predict your cycle timings, and the fact that sex at any time in your cycle could result in pregnancy.
However, the Lady-Comp boasts being far more accurate at tracking your cycle and reproductive activity, and thus being able to detect subtle changes a person may otherwise miss indicating when your cycle is not going as planned. Some users claim the device can help them know when to use emergency contraception if necessary.
It does not appear to be listed among major reproductive healthcare providers, articles, and organizations. Without their input, I feel uneasy with vouching the method myself. But this will likely change with time.
