Glad everything went well..

I just had the iui injection today. bit cramp when injecting it and feels like gonna vomit after that. I will have to inject Pregnyl in that period.
So what i want to ask is..is there do and dont after you have the iui?
They told me that i will have last blood test to check if positive or negative in the next 2weeks..
Do you think if i check earlier will show positive / negative ?

Thank you
