Pregnant or Not.Okay so a Boy and me had sex unprotected a few times.?

[Sade]

maybe 5 times. Um one time i took Plan B,and Day after pill which is only good 3 days after unprotected sex.So the next couple of days we did it again.I saw white stuff when he pulled out,but he said it was me who came on him.His friends and him made jokes that i was preg. I said no you have to be kidding and then i started to believe them until maybe 6 days later i had Pink spotting i thought was my period but i heard it could be bleeding that u get when u are preg. called implantation. but um yeah i experience Headaches,dizziness,stomach aches sometimes i feel like i got to vomit,but i dont,little cramps here and there and im not myself i love to keep busy but i want to relax now.and its been about 3 weeks after.i took a test 2 weeks ago while the light period was on but i knew it as too early to tell.now its 3 weeks should i take another one or wait.
