Brown Lump in Urine

So, today, I was peeing and then I looked down and this appeared... I took the Take Action pill three days ago because I was worried about pregnancy. I'm still a virgin. But he had precum on the tip and he rubbed it outside my vagina. Is this brown lump a sign of pregnancy, is it telling me that my period is coming or is it a pill side effect? Please help, I'm really freaked out
