Any insight on these test results?

Melissa

My period was just 16 days late, got my hopes up but again I wasn’t pregnant. My Dr ran some tests, my values fall into “normal” range but does anyone have any more insight? Why if everything is fine was I so late. I haven’t been more than 1 day in 3 years. I’ve had an ultrasound before also with no signs of PCOS.

Tests were done on Cycle Day 3

LH - 2.6

FSH - 6.1

TSH/THY.STIM.HORM - 1.34

Estrogen - 211.9

DHEA - 127
