If i had covid-19 end of september/beginning october, am i at risk of getting it now?

COVID 19: There have been cases of repeat infection reported but this is rare. It would be unlikely that you would be re-infected with the same strain of virus.

Yes: There is evidence from many cases that persons who have had covid can catch it again after 3-4 months. The repeat illnesses show less strong symptoms and last a shorter time, but seem like they are more likely to lead to long term problems such as chronic memory problems, sleep issues, smell/taste anomalies, changes in lung function and inflammation of the heart muscle/kidneys.

Essentially no: Of the millions of people who got Covid 19 the number getting reinfected can be counted on the fingers of one hand. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV vaccine. Wish you good health!

Too soon: Having had COVID /19 i understand your concern but you have built up antibodies for at least 4-6 months or longer. I would get the vaccine when you can as i will do the same.
