This is my first month using the 28-day pill. I have taken all of the pills on time, haven't missed any and have regularly been having sex without a condom. I am on the fifth sugar pill, and according to the packet I should have got my period two days ago. I had some fairly heavy spotting for a bit a few days before the sugar pills but nothing since the sugar pills. Will this upset the cycle, and am I still protected from pregnancy? Should I keep taking the sugar pills until I finish the packet and then start the new one?
