TTC confused

Heather
So I have been off my bc for over a month and I was supposed to get my period Oct1st or so I thought. But AF hasn't come and I've taken two EPT's last week out of excitement and couldn't wait but they were both BFN. Still haven't gotten my period, was I just off of when I was supposed to get it or did I test too early or maybe my body is just off now from not taking BC anymore?? 😕 any thoughts/advice would be much appreciated. Oh and we have only been trying for the last month so not that long, and I know it can take a while after stopping BC.
