Temps Near Coverline

Amanda
So, this is my first month charting with a real BBT thermometer. Curious if my chart looks ok or weird - the past months have been all over the place! I already feel like giving up hope for this month because my post-O temps are below/so near the coverline. I'm 3dpo today with a positive OPK on 8/20 and 8/21. 
Any insight would be awesome! Every morning I am so nervous to take my temp :-/
