Has anyone else had their JAK2V617F mutation disappear completely and then have a TET2 of unknown significance come up? Only on aspirin?

First diagnosed with ET and JAK2V617F was low alle burden. A year later no mutation, 2 years later still no JAK2V617F but acquired new TET2 mutation with unknown significance and mild fibrosis that was not there before. Im only on baby aspirin, nothing else.
