Plan b…

Ok I’m panicking… I took a plan b on the 1st. My period ended last month on the 30th.

So a day after my period my bf c* inside of me… I started bleeding on the 5th so 4 days after the plan b, really bad cramping, was enough to fill up a pad. So technically my period was due the 25th - my trackers, but usually I get it the 26th. So Idk if I’m a day late or two… anyways still no period insight, I have cramping though. Has anyone taken plan b & had a late period? I’m getting n* because I’m thinking I’m pregnant, I’ve taken plan b numerous times before but it was yearsssss ago, I forgot what side effects I had. I took a pregnancy test this morning & it was negative.
