I have been on Tri-Nessa for 2 years and this month I accidentally took the sugar pills the first week of my pack instead of the normal ones. I took 2 one day, three the next, and two each day until I caught up. My husband and I had unprotected sex a couple of different times while I was still trying to catch up on my pills. My period is still a week away, but I'm having heavy brown discharge that I've never had before. I'm also getting terrible cramps, feeling sick, and headaches. What do all of these signs mean? I have pored over the internet trying to find out if I'm pregnant, because I don't want to wait until my period comes to find out. Anyone that can help, I would IMMENSELY appreciate it!!
