HCG booster 1500 iui maximum nausea time?

Maria
Hi all,
Just had my final 1500 iui booster a day and a half ago. I know I just need to wait it out, but it is the first month, and I am always an early tester so this is killing me! Now have constant lower abdominal ache, and increasing nausea, +++ just tonight despite water etc.  
so I was wondering, for those of you who get nausea with a trigger or booster, when is the peak?  For me, with the trigger for ovulation it was six hours post, and lasted three or four, and was just like morning sickness, then went away.
