You have a better chance of conceiving if you have sex during your ovulation window or a couple days before hand. Try have sex every other day starting a week and a half after your period
It is possible, some people have periods still through out their whole pregnancy
What matters is did you have sex sometime within a week from you ovulation date? If so, then Id say yes, its possible.
What helped us when conceiving was knowing my ovulation period and maximizing that time. I used an app, but you can also use special thermometer to be more accurate.
Good luck!
Unless you are ovulating than the chance of getting pregnant is slim but not impossible.
