For my part I use this monitor, handheld mini-computer as a contraceptive and I can say that of course there are no side effects, it is very easy to use. We use it for 15 years because before it was called "PERSONA". It is true that the device is expensive but mine still lasts! So much cushioning also for the tests must "test" several pharmacies because prices can vary from one to another. Some pharmacies may offer a demo (especially if you theirs request) with a presenter from the laboratory to explain the operation which is basic. about 6-7 urine tests to the toilet ... and you are alone, the machine tells you if you are fertile or not, if you have ovulated, if your rules are coming soon, etc .. However, it takes three months for the machine to test the functioning of your body and records the data, during which he must be careful. So I also recommend this CLEARBLUE appliance excellent alternative to the pill especially if you support no side effects, and they are many of the latter.
