I'm also pretty new.. nearing the end of my first crop since I was a teenager lol.. however I could tell in a fraction of a second by glancing at that first pic it was definitely female.. I know what it's like to be new and paranoid... wont be long now though man.. I felt the same way a month ago now I'm thinking I have to crop one early cause I have overgrown my space and the humidity is out of control... good luck dude
