Okay well I got the Juneel Fe 1/20 28 day pills. The ones with the three weeks of yellow and one week of brown pills. Anyways I read the little "how to use" sheet and stuff but got confuzzled on one part. Its says to take in within the first 24 hours of you started peroid. I started my peroid on the 12th this month and well its now the 15th so can I start taking the pill or not? I don't think I can but I'm not sure. Also what are the brown pills for and the yellow ones. The paper that came with it didn't really explain everything good enough for me.
