After the launch, the Welsh Blood Service continued to promote the introduction of the new rule over a 16-week period (one full cycle for donors) via SMS and social media updates.
Ar ôl y lansiad, parhaodd Gwasanaeth Gwaed Cymru i hyrwyddo rheol newydd dros gyfnod o 16 wythnos (un cylch llawn i roddwyr) drwy negeseuon SMS a negeseuon ar y cyfryngau cymdeithasol.
