Light periods, please help im so worried 😦 😨😨😨

Okay, so for a year now i’ve been having slightly lighter periods than i usually used to have before since i got it at 12. Im 19 now. When i first had a light period, i worried but somehow passed it as a normal thing, thought it would change back to heavy the next cycle. But it didnt. I used to fill pads within 2 hours and now i barely fill one within 5-6 or maybe 7.

It is still regular though, every 28-30 days each month.

The first day it starts of as spotting, turning into a flow during the day, the 2nd is a medium flow-filling pads and i also pass clots , 3rd lighter, 4th is spotting, and 5th too ( if there is one). I used to have a 5 day full blown period.

I checked with a doctor and they did bloodwork and turned out my prolactin was quite high above the normal range so i took cabergoline which took it to the normal range. I thought id get my normal period back after i have my hormones in track but still the same. My obgyn told me i didnt ovulate mostly during my light periods until i took cabergoline.

I don’t know what to do anymore, i have an appointment for another bloodwork tomorrow where they’ll check my levels on all the hormones. I am extremely worried that I’m not even ovulating and this way i wont be able to conceive whenever i want or ill be infertile.

Has anyone had this happen? How did it turn out, I’m devastated...
