Might be pregnant?

So i just got off what i think was my period. It was about 6 days long with super light bleeding then one heavy day then back to light. My thing is my BF kinda finished in me but pulled out when he realized. And that was 2 days after my period. I've been cramping and been getting sick around food or even if i eat. And if i do eat i can only eat a little before i throw it up. I took a test at 10am when i woke up but it was negative. Is it possible that i am pregnant but its just to early to tell? I have had white discharge but nothing else.
