Sister Four Months Older

How is my sister 4 months older than me? OK so both my sister and i are 16 years old and she is 4 months older than me, and only today did i realize that you can't get pregnant while you're already pregnant (only in rare cases), our mother must've been 5 months into her pregnancy while i was conceived, is this a case of superfetation? Not trying to debate anyone, just want to understand Edit: Turns out my dad had an affair with his cousin

A Reddit post asks how the writer’s sister can be four months older despite both being 16.
