I’ve been on the pill for about 4 years. Before, my periods were 17 days and really really heavy so when I went on the pill it lessened it to 5 days of extremely heavy periods. This month, I was 4 days late and it was basically nothing, I had to wear one pad on day two (thurs) but there was only a few drops on it, nothing big. On Wednesday I started a light light bleed like a pink brown then on Thursday it got slightly heavier but nothing significant. And on Friday it was totally gone. Is it normal for them to just change like that after so long on the pill? I do have unprotected sex but I’ve tested today (Sunday) and it was negative.
