Hello,
Sorry, unable to understand your question.
If you got your periods in 2nd may 2018, you would be getting it again on 31st of may 2018 or 1st June 2018.
If your expecting date was 2nd may 2018 and you haven't got your periods than you need to do following test.
1. Ultrasound of abdomen and pelvis
2. UPT
3. TFT
In many cases, it's normal to have periods late for 3 to 4 days.
If the duration is more, you might be having PCOS,
Thyroid disorder, etc.
But before coming to any diagnosis you need to do the above tests.
Next Steps
You need to take medications for same after proper history taking.
I would suggest you to take consultation online.
Medicines will reach you via courier.
