Two weeks before next period po if regular ang menstrual cycle niyo. Try keeping a period tracker app on your phone, I suggest using Flo, it's on Google Play. You have several days within the ovulation period to try conceiving. Tip: When making love with hubby, don't try to think that you're trying to conceive. Just enjoy the moment with him because if you're over thinking it, it's not gonna happen. Mas nakakabuntis po if you try it that way. By not trying so hard to make it happen. 😊
