Should we try tonight?

Ok should we baby make tonight or no? I wanted to try the shuttles method and try for a girl by having sex 2-4 days before ovulation, but we’ve been sooo busy out late every night that we haven’t even tried... I’m supposed to ovulate tomorrow. And this is my test result... anyway I have a few boys and REALLY want a girl, should we try tonight- even though it’s the day before ovulation or should I just try again next month? Did anyone have sex the day before or day of ovulation and conceive a girl?
