First month TTC!! Any tips?

HI! this will be my first time trying for a little one. I have one little boy and a baby girl in heaven(both were surprise babies when I was very young in a previous relationship). My SO has no babies of his own and we recently decided it was time to give my boy a sibling!! Anyways so I just wanted to see if any of you beautiful ladies have any tips for me or even just decipher some of the slang used on here? I don't want to go gung ho at first (ovulation sticks, BBTs, etc) but maybe timing or positions, or anything else that would be helpful. Thank you in advance!!
