Should I remove the OvuFirst Sensor before having sex?
There is no requirement to remove the OvuFirst Sensor before sex, though you may find it more comfortable to do so. If you do take it off we recommend that the OvuFirst Sensor is put on again after sex to increase the amount of data collected. The OvuFirst Sensor is designed to discard temperature data which are not within the normal body range so any data collected when not in use will be removed.
