Negative ?

We have been completing lateral flow tests twice a week now more many many months.
All , so far have been negative but with the incubation period from contact with infected person to positive test being up to 14 days, is it really worth the plastic it is recorded on ???? I am not thinking of stopping testing but realise that potentially, I could have / could pass on Covid in those 14 days. So, therefore could other people at venues/ in the street/ in the cafe etc who have had negative tests.
Omicron is apparently rampaging through the country with the threat of further restrictions ever hanging in the air. We don’t have real data re what, if any, real dangers it poses.
Despite being ‘triple jabbed’, I find it so difficult to know what to do for the best.
