AM I PREGNANT VERY URGENT

I’m on birth control and throughout this pack (I’m on the 2nd week) I have been taking it every day except for once I forgot and made it up by taking two the next day like your supposed to. After that i then took it consistently for 4 days and then I slept w my boyfriend, that night I forgot to take it again and the next day I made up for it again.

So here’s what I’m questioning ..

So that day and the next (today) I’ve been having brownish red discharge but it’s only when I wipe after I use the bathroom and it’s very little. I’m also getting cramps once in a while ..

I got my period last time March 20th

am I pregnant and should I take plan b

Pleeeeease help
