Miss pill and period. Straight away.

I am currently taking the pill (microgynon) as a form of contraception since roughly January of this year. I have no problems with it so far and have been taking it on time and have not missed any days. This was up until last week (2nd and 3rd) I forgot to take the pill both days. I then read up and saw I needed to take two on the 4th and again 2 on the 5th and then Continued to take them as Normal. However on the 4th I began to bleed as if I came on my period and have been since so far today (12th) hasn't been regular though as has sometimes been clotted and very dark brown. Not sure if this is normal or what to do. I am due to take my seven day break on Sunday 14th so am unsure if I will bleed again or whether I should not take a break and start my new pack straight away.
