I had unprotected sex on Jan 27th, i took Norlevo morning after pill the same day about 2-3 hours after. It was the day after my last period. My next period was due 9 days ago and still hasn't came. Ive heard that this pill can delay your next period? Ive taken 2 home pregnancy test both came back negative. Any help or advice would be appreciated as Im very stressed and concerned that i might be pregnant??
