For almost 1 year & 2 months l used Pills as my protection. I had my last period July 31 but my pills for the month of July will be ended august 1. I started my new pills august 2 for that month. Sadly august 4 I refused to took my pills that day and I had sex with my husband that day. After that l remembered that l forgot to took my pills. Am I pregnant?? Please help me??
