Help! I need answers quick?

So I've been in the pill for a while now and I'm not meant to have my period but I do and I'm not sure if it's because on Friday and Saturday I missed my pill so I took 2 on Sunday and 2 on Monday then started taking them normal again so I'm back to normal and on the right dates now so I'm questioning if it's because of that or if it's something else can someone please help me?
