Discharge TMI

The other day I went to the bathroom and I saw some pink in my underwear with some discharge. I have irregular periods. lately it’s been 38 days between periods. I’m TTC could this be a sign of pregnancy? My period isn’t supposed to come for 8 more days according to the app if I go off of the 38 day mark but I usually go 34 days between periods? Should I test now or wait longer? I’m being so impatient
