Helpppp!!

Okay so you ladies use the app so obviously you know it logs your period as well. I'm supposed to be on day 5 of my period according to the app but I've only been spotting suuupperr lightly off and on for those past 5 days, I haven't worn a tampon AT ALL and there's been absolutely no blood on my panties. I have had headaches an sore boobs like I'm on my period but not bleeding. I've had sex with my bf for the past 3 days and we usually do almost everyday lol (I know, I know tmi). I am just wondering if this has ever happened to any of you ladies? I'm nervous and have been super stressed lately and find it so hard to drink water so I don't think I'm prego but it is possible! We aren't trying but we aren't trying to prevent a baby either. Please let me know if this has ever happened to you! Should I take a pregnancy test or just brush it off?
