should I test?

Moms my lo is 3 months old. I am not breast feeding. I had my first postpartum period oct 4-7. I normally have a 30/31 day cycle. My hubby and I are using condoms and pulling out method but now my period is a few days late with no sign of showing up. 
Midway through my cycle I noticed ovulation discharge and a few days after that I noticed pink tinged discharge. And instead of the normal preperiod no discharge I have had SO MUCH clear mucousy discharge. 
Is it possible I'm just freaking myself out or should I test? Pic of my bubbs because I'm not ready for him to have a little sibling 😅😅😅
