Late period but..

Late period, I've only been late once before and it ended up being my pregnancy in which I miscarried. No sex since before my previous period.. Not under any particular stress. 
I know my mom personally had monthly bleeding during her pregnancies much like a period just trying to get some feedback. I just want it to be here so I can get it over with, my hopes aren't particularly up or anything since I did have one after my last intercourse. I'm a very regular and spot on 28-29 day cycle I'm at about 33/34 so far and all my apps telling me I'm late is freaking me out lol
