Progesterone shot and Period.


I took my first progesterone shot nov 27 I was supposed to get my period till December 3 and my doctor said I was ovulating so I took the shot on the 27th and the next day I have some light pink spotting I’m not sure if this is my period or an effect of the progesterone shot ethier way im fine with it but my office is closed for holiday so I have no way of asking if i should continue shot even thoe spoting.? I was wondering if anyone takes this shot while they’re on their period Or stop until your new cycle starts thanks sorry for my bad grammar
