Clomid side effects?

Hi I took clomid for the first time this cycle days 2-6 at 100mg I had a 5000iu trigger shot of pregnyl on cd9. Today is cd 14 and I've been throwing up all morning can't even keep liquid down? Does anyone know if this is a side effect from the clomid or a side effect from the trigger shot? I've had negative hpts since triggering so not even sure if that worked in my body as I've had positive opks since cd11... any advice would be really appreciated. Thanks molly xx
