Failures

Below we have listed some negative testimonials that we have received over the past years. We don't receive many. Nevertheless we like to publish them to point out that PERIMON (as every contraception) can fail. We therefore recommend you to additionally use the mucus and/or cervix observation method.

You can also visit our positive testimonial page. You are welcome to look at the German testimonials and use the Google  translation service.

Ich verhüte mit [PERIMON] und mit Kondom [...] Einmal bin ich schwanger geworden, ungeplant, habe es aber gleich wieder verloren. Schwanger geworden bin ich darum, weil ich aus verschiedenen Gründen plötzlich sehr unregelmässig die Periode hatte. Nun klappt es aber wieder sehr gut. • Mondstern, 05/15/08

I have been using Perimon for quite a while and I had also considered it as working extremely well. However, probably because of stress, my cycle changed [...]. I got pregnant and the doctor said that the conception was around 2nd to 4th June. My period ended on the 2nd and we never have sex during that time. So it must have been after the 2nd. Days marked by Perimon as green – infertile.

The software PERIMON has been distributed via the internet since Sept. 2001 (after a test and development stage of six years).
