What is this?? Tweaks please!

Am
Is this a faint line, indent, color run, evap? I am getting ready to start the Phen375 for weightloss soon and wanted to make sure all was good before starting it. I havent had my cycle since December 15 but I have PCOS and endo, so, really its nothing new- but i found out i was pregnant with my son after a spell like this so i just wanted to double check. I will retest in a few days but wanted opinions. Thank you all in advance
