After egg collection

Had egg collection this morning had a good number of 12. They was pleased however I'm still feeling uncomfortable not as bad but tender bloated and pain when I bend or go to sit down. Is this normal. Also started progesterone pessary tonight I think it's made me feel faint as I had dinner half hour or abit after and I become very full and nearly fainted is this becasue of the pessary or because been fasting since last night? Many thanks
