should I take a plan b

iona

I’ve been on the mirena iud for about a month and a half now, and i’ve been irregularly spotting/on my period for a month straight. I got nutted in today by my boyfriend and i’m a very anxious person and even though i have an iud I feel like I should take a plan b but I know that it can mess up your cycle... would it be extra to still take one or no lmao
