Yes, possible yan! If your period lasted 7-9 days, then by day 12 you're already in your fertile window, most women ovulate around days 12-16 of their cycle, so you could definitely get pregnant then. A few of us moms actually got pregnant right around that timeframe, kaya fingers crossed for you! Just make sure you're tracking properly and having regular intercourse during those fertile days, plus take care of yourself, vitamins, healthy lifestyle, all that good stuff. Sending baby dust your way, mama!
