Pregnant? or just symptoms of IUD removal?

so i just had my mirena iud removed 4/13... two weeks ago... i had unprotected the day before is was removed and just about every other day since. i didnt bleed much when the iud was removed... it was light and lasted for about a day and a half... 3 days after i stopped bleeding i bleed a tiny bit... just showed on my panties a bit and when i wiped... that lasted about 3 hours. could that have been implantation maybe? well... now it is 2 weeks later and im tired, im getting headaches, my feel much heavier and my are sensitive, ive had small cramps in my uterus, ive been constipated, ive been having hot flashes and then chills, ive been more hungry, had some mood swings, and ive been queasy but havent thrown up.... im 20 years old and in perfect health... before the iud i had normal periods and during the iud i had light periods with minor cramping and ive been going pee more... i know its 2 early to take a hpt... but I REALLY HOPE IM HAVING A BABY! and i cant get off the internet and stop researching my symptoms... so i thought i would see what others thought :) so... do you think im pregnant or its just iud removal?
