Day 38 Still No AF

Hi Ladies

I came off the pill beginning of Oct 2018 had my withdrawal bleed, then 33 days later had my 1st normal period. Now I’m waiting for my 2nd period. I’m normally 31-34 days before the pill but was on the pill for 4 years. I’m Day 38 and still no sign of AF 3 pregnancy tests have been negative.

Is this normal after coming off the pill or should I be worried?

What do people think or suggest?
