Talk to Gynecologist on Delay In Periods

I had my last period on November 26, 2024. Since then, I have missed my periods for the months of December and January. On February 5, I consulted a gynecologist, who prescribed a 5-day course of Primolut N and advised me to undergo some tests on the second day of my period. I completed the course, and on February 15 (yesterday), I started experiencing spotting with a few blood drops. Throughout the night, I had period pain, but when I checked my pad this morning, it was empty. Even now, I am still experiencing period pain, but there is no bleeding. Should I get the tests done today, or should I wait until my period becomes more regular and I start bleeding properly?

The tests are Serum FSH, Serum TSH, Serum LH, Serum Prolactin, Serum Fasting Insulin
