My period is late

October 2015 I lost my son to my cervix open up when I just make 22 weeks pregnant. I'm still grieving over my son death. It's been very hard on me still. Now April 2016 I decide to try again & this month my period haven't came yet. I been having a period all the way to now. I want to take a pregnant test but I'm feeling a way where I'm going back & forth thinking well this month isn't over yet but my period would have came around the 13th of each month & it haven't yet. Should I wait until April is over to test or go ahead & take a pregnant test now?
