Late period after starting levothyroxine 25µg

Hi, I started my medication for hypothyroidism about a month ago. I’m currently 4 days late on my menstrual cycle, I’d like to mention that my last period only lasted 2 days and a very light blood flow. I’m a bit concerned as my cycle was precise my entire life. Female, 22 years old. Any ideas if I should also see a gynecologist? Most posts that I read about levothyroxine actually say it helps regulating an irregular cycle, which like I told you, my cycle has always been on point
