Not sure when af is coming??

I was on the pill for the past 12 months, I accidentally missed three pills last month and since the next weeks were the placebos I just didn't worry and let me period come.  Well it came early and ended early so I wasn't sure when to start the next pack, so stupidly I still waited in the Sunday start which left me not taking a pill for 11 days.  So my husband and I just said oh well if we get pregnant we will be happy but are not trying yet.  So now my question is when is my period due? Will my body just keep my normal cycle or will It come when it was supposed to and just be longer then normal?   I don't know if I want to start the pill again next cycle be we want to start trying but if I am pregnant Idk when to expect af?? Help :(
