Can you have complications from covid once you recover? like can you develop complications post covid months later?

Hard to know. As a disease we have limited long term (several years) information on it is hard to know what the long-term outcome will be for recovered patients. To date, most with mild disease have few longer-term problems.

If you recovered you usual health, the risk of any complications developing later is remote to nil. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV, Flu and Covid vaccines. Wish you good health!
