pregnancy?

so when i had sex we didn’t know if he came inside me or not because i felt something, but we had to make sure by taking the take action pill. so i thought i got my period because it came randomly after 2 weeks, but it was brown. every time i wipe myself it’s brown and only a little bit. my pad is usually empty for these past 2 days but i’ve been feeling little cramps here and there. reading things on google is the worst because it makes me overthink so much and i get so much more stressed and i trust you guys more than something that comes off google. please help and tell me what this is
