I had unprotected sex approximately 6 days before I missed my 3rd last active pill before the sugar pills. When I realised it was more than 24 hours so I didn't take two I just continued on with my pack, now that I am on the sugar pills my period is very light with a lot of brown discharge at the start. could I be pregnant? Will I be protected when I start back on the active pills? Or do I have to wait until I've taken another 7 active pills.
