Anyone else nauseous early in 2 week window. I’ve 8 days to wait for prey test but Woken up in the night feeling really nauseous. SO sudden i though it was something i ate but i havent been sick, just nauseous. Still feeling this morning . Also have a ‘drawn’ feeling in my lower abdomen. 
Anyone else had anything similar or was it what i ate last night.
