Its called 'google dance' its completely normal behavior for non-established sites after they gain backlinks, you should either not do anything or keep building links at the same velocity as before. It will take some time (days or weeks) before rankings settle.
Spend more time and effect on SEO activities. Review again the backlinks you did then disavow any links that were marked as low-quality.
If it's coming and going I wouldn't worry much about it. It's annoying, but it's not like being deindexed. THAT is a problem, and can often take months to recover.
