To test or to wait....

My 17 month old has been way more clingy than normal for the last week. Today is day 27 of my cycle, I have always been able to test and know I was pregnant at 3 weeks with both boys. I have none of my normal af is on the way symptoms. I haven't tested yet because I just had my iud (mirena) removed in July and was taking the last 2 months to make sure I was tracking right. Should I test tomorrow or wait till I'm sure af is not coming?
