I have been on Junel for about 3 years now. I had sex October 14 2015. He wore a condom and didn't miss any pills at all. It was a little big on him so I worry about the cum seeping out. The next day I was put on antibiotic. I got my period a week later on time and normal. The next month I also got my period. And this month i got my period on time, just today. It's lighter and I don't have many cramps. Could I be pregant?
