Tww over, 3 days late no bfp

Sr
My periods was supposed to start on the 5th of October. I have pcos and my periods are almost regular(28 or 29 day cycles). I am getting BFN all times even with fmu. Last month doctor said I am ovulating normally, so try for a year and if not happening we can proceed with some treatment. I have most symptoms but not sore nipples. I literally have no signs of my period. Usually a few days before my period I have pain in my calves and pain in abdomen. I am not sure if I am pregnant or just late on pms. This is our first month ttc for our #1 rainbow baby. Please pour in any suggestions what to do now. Thanks a lot guys for taking time to read this :) baby dust to all of you :)
