Confused🥴🥴

Ok when TTC and you get your 1st positive opk when do you actually ovulate or do you need to continue taking opks... Because I had sex on 3/5 and twice on 3/6 today is 3/8 and I got a positive opk according to glow so do I still have a Chance because my partner has to leave for his job so we won’t be able to BD again until maybe 3/10-3/11
