plan b

so I had unprotected sex a week ago. He pulled out but I took plan b about16 hrs later. I realized I was in my fertile window but didnt ovulate yet. I believe I ovulated about 2-3 days later. Im experiencing some cramps here and there, bloating, and moodiness. My period is due around the 16th. I usually get PMS symptoms about a week before my period. I keep track of my cf and cervix position. TMI but Im completely dry (no cf) and its in a medium firm position. I think Im gonna get my period but Im paranoid. I haven't taken plan b before so are these symptoms normal?
