I was on bc and I missed a few at the start of the pack directly after the 7 day break. Then I ended up changing packets because the filler in one of the pills made me really sick,

I spotted earlier in the month, maybe 6 days ago? I thought it was because I stopped taking the pills because I normally bleed full on for a week after I stop my pills and its normally really heavy, but this lasted one day of normal blood but only when I whiped, then brown discharge the next day. But now I have no idea when I am meant to bleed or when to test for pregnancy
