Bloody Surprise

For the past week or so my period has been reddish-brown and pretty light. All of a sudden at 3am on a Tuesday I feel it start (you know exactly the feeling when the pink sea turns into the red sea). I’m not even gonna lie, I’m mad. I’ve been wearing my old smaller tampons because the bleeding was kind of inconsistent and about 30 minutes after I take it out I bleed onto my sheets. I’m pretty pissed actually. But this raised another question for me: If I don’t have my period for several months at a time, the next time I have my period, will it be a collection of the multiple months or is it just whatever is in there from one missed period?
