Too early?

So early this morning about 6am, I woke up and had these terrible sharp pains in my stomach. Then later on I started getting cramps in uterus area, & a while after that I started throwing up. I've been nauseous & had a metallic taste in my mouth all morning. The nausea is so bad if I stand up too long, I have to head to the toilet because I'm about to puke. I'm only 7dpo, is it too early to be having preg symptoms? I want to test so bad, but I know that's too early.
