Confused!

I am coming off the pill and stopped taking it on NYE. I had my withdrawal bleed as usual from 4 to 7 Jan. I started using one step OPK from CD 11 at first in the morning and then twice a day. They have got to a semi faint line and then are now back to barely even a line on CD20. From about CD15 I have had bad cramps on and off (these have subsided a little), really sore nipples, nausea and lots o EWCM but that stopped a few days ago. All the physical signs point to saying I have ovulated but sticks say no. I’m confused as to whether I should keep BD or even when I could try take test as no idea where I am? Anyone had similar experiences? ThBks
