Should I take a pregnancy test?

li

I've missed day 1 of my period, which occasionally will happen to me sometimes. But usually not, my cycle is really pretty consistent.

I haven't really had any sign of period, usually I get a lot of cramping in my lower back and body aches. I haven't had any of that. I haven't had any discharge like I usually do before my period. Just a little bit of creamy white discharge (normal not itchy or yeasty)

Should I take a pregnancy test, or should I wait a couple more days?
