Getting engorged again help!

So I produced more milk than I needed at first and was always engorged the first month but my body seemed to regulate all last month which has been nice. My daughter is a little over two months old and has been waking up only once at night for weeks and my milk supply still seemed normal but all of a sudden the past two nights I’ve woken up leaking and in pain. Any ideas why this might have started happening again? Sorry if this question seems dumb, ftm.
