First Month Trying!

Hi ladies I'm new to this since it is my first month trying!!! I've always kept track of my cycle and made sure I was having unprotected sex on the days I was most fertile. But today my period came:( Any tips ??

** I did notice that when my partner would cum in me it would all come out afterwards... is that normal?? I've read post that suggest to lay in bed afterwards and others that say it doesn't matter... Any thoughts on that
