pregnant??

first off I just wanna say I’m on birth control but anyways I had protected sex with my boyfriend on July 28 and then after he took the condom off and went in just a couple times raw. after I stated freaking out and he rushed to get the “take action” pill and I took it. my period is supposed to start this week. Yesterday and today I had a weird brown discharge and been cramping. I’m freaking out bc idk what’s going on with my body. I’m praying I’m not pregnant i just started my senior year and I’m not ready!

Please give me some advice! 😭
