Late and no tipical symptoms

Hi everybody.

So according to Glow I'm 5 days late which is weird because my period is usually like clockwork.

I have no nausea or tender breast but I have been a bit constipated with hard stools until today which was much softer and had like an orange tint to it.

My stomach is also grumbling like crazy and I have super mild headache from time to time.

I had light period like cramps last week with a light yellowish discharged but it has mostly subsided and some back pain yesterday. It constantly feels like my period is going to start anytime with a heavy feel down low.

Any thoughts, I'm too scared to test.
