What Are The Uses And Side Effects Of Cytotec Pills?

I recently started a medical ab. I went to the clinic on Thursday 9/23 and took mifepristone at approx. 1:00pm. I was sent home with 2 sets of cytotec (2 200mcg pills each set) and was told to take them at bedtime on Saturday 9/25 and Monday 9/27. I took the first set at about 7:00pm on 9/25 and had a very small amount of bleeding. I have 2 questions. I was wondering if the small amount of bleeding is normal & also if it is okay to take the second set of cytotec pills earlier than bedtime today since I have the day off. thank you in advance for any help or advice!
