Quick question. Should I just go buy a test now?

Heyyyy ladies! So. I’m going to get straight to the point. According to Glow I’m late for AF. My cycle is on average 25 days occasionally 24 or 26 days. So I guess I would be 2 days late? Whatever, point is I’m late. I’m debating whether I should get out of bed and go buy a test now or see if my period eventually comes. What do you guys think?

SN: Besides a missed period, I’ve had a cold for coming on 2 weeks now which I didn’t think could mean anything until I missed. I noticed probably 3 drops of blood last week which again I didn’t think was anything. I’ve had bad headaches every day since day after Christmas which was apparently the day I was due for AF
