Late?

Question

I'm normally 29 days 
Glow is not telling me my period is for 4 more days but today is cycle day 31? 
No period haven't tested yet.
This is my 3rd cycle trying but I think I ovulated late too. I don't know for sure cause I ran out of tests right as they started becoming almost.
Used pre seed and bd as much as was possible. 
I don't want to keep waisting tests by testing early or when I'm not.

I've been super super
Emotional and had pretty intense fatigue but I've also been stressed and
Not sleeping well-
I usually get cramps for ad comes but nothing really yet some with back pain a few days ago but nothing sense ....

I dunno. 
I'm super bad at giving myself symptoms so I've been trying so hard not to think about it my or stress about at least ttc since I just got a huge promotion and we are trying to buy a house all at the same time. ( which isn't being successful)

I think I'm just distracting so I don't test. Thanks for listening. Let me know if you have any input.
