Trying Again!! Tips needed!!

So since AF showed a few days ago, I want to TTC again. So I would like to know all the tips and items I can use to help me out this time around. Oh and just to let you all know, last time I only just tracked my period and went off based on what days the app said I was fertile, which didn't help, so I wanna do it differently and better. So ladies, if you all don't mind. Tips and tricks and help needed... Thanks in Advance! 😊
