Plan b during ovulation

Yesterday felt extremely weird and off..felt like AF was supposed to come but that was the 10th. Felt very nauseous at a restaurant that I never get sick from..dizzy headed/headaches, back pain,fatigue, bloating, cramping..took plan b w/o thinking it had a weight limit. I’m over 165lbs and was ovulating at the time when I took the med. Took HPT came out negative..symptoms increase everyday. More moody than before..
