Too Early for Symptoms?

I took clomid 50 mg this cycle and I am on day 22 of my cycle and for the past 5 days I have been getting nauseous and I ate birthday cake this week and well I ended up throwing up after wards. I also been having burning sensation in my nipples and been getting cramps off and on a little higher than where I get my period cramps. I know its way to early to test but all of these symptoms lead me to think that the clomid worked. What do you guys think?
