In a Curriculum Vitae you normally only state the important previous employments. Like long term employments, or important to know employments (for you or your possible future employers). Nobody is interested in a long list of all your previous jobs. As you already stated : a too long list could elicit more questions and be used against you.
So keep to the main ones, and specify in continuous longer periods like (half) years, rather than "day by day" or "week by week"! Remember : lying is always wrong, but some leeway is allowed to keep your CV on a single page format!
Note : always the last job on top and the oldest one at the bottom. The lower on your list, the more flexibility and abbreviation is allowed.
.
Success!
