Might be Pregnant???

My menstrual cycle returned last month on April 19th, after 16 months without a period. I'm still breastfeeding my 17 month old daughter. According to my glow app I'm 5 days late, and according to my Flow and Ovia app I'm 3 days late. I don't want to test and have it be negative. My menstrual cycle has been a week late before, because of stress. My husband and I did have unprotected sex during my most predicted fertile days. It would be a blessing if we are pregnant again. However, I just got a job as a housekeeper at a local hotel to help out financially, since my husband lost his full-time job. I haven't had any symptoms of pms or pregnancy, except a wave of nausea, which could have been caused by the Georgia heat and not being properly hydrated. What should I do? Should I wait a couple of days before testing or go ahead and test?
