first month TTC! give me all the advice!

Hi everyone! DH and I are TTC for the first cycle ever! I have no idea what to expect. I've been charting since October and my cycles are very regular and it's usually very easy to pinpoint when I ovulated. December was weird due to a change in schedule (I'm a teacher) but my current cycle has been good so far. 
Any advice for a first time TTCer? I don't want to get stressed at all, but I also already feel so excited!!
