If you've opted to monitor your glucose with 2 sensors every month, your sensors will cover 28 days of monitoring (each sensor lasts 14 days). Each month, your billing happens on the same day, which triggers your shipment to go out on the same day or next business day. This generally results in a few day gap after each months' sensors.
If you want to have no breaks in between your sensors, we are able to charge your next renewal at an earlier date. This will mean that your next set of sensors will ship while you're still using the previous set. Just let us know by messaging us via chat or emailing email@example.com and we'll be happy to help!
