Next choice- one dose

myranda • 18 y/o, been exclusive with my boyfriend for a year and a half. Enjoys longboarding, working, and snuggling with my two (soon to be 6 with the upcoming puppies) bichon frise/shin tzu mix`s
I just took it like 20 minutes after a possible slip up. Has anybody had any bad side effects? It says nausea, headaches, late periods, etc on the box.
