Brown spotting and no cramps?

[Starlight288]

I'm new to TTC and recently off BC. I've had 2 " normal cycles" as in they came around the same time. I had a normal flow ( heavy then light ) & the cramps I usually have ( even on BC). This month, I'm due today and yesterday had some pinkish/red dishcharge and all brown now and barely there. I have no cramps either! I was using opk and got a positive on 12/9, so idk what's going on. I've not had a tons of symptoms, just major bloating & some crazy dreams the past few nights. I've also had weird gurgling but I chalked it up to AF but she's not shown yet. Took one test today BFN. Anyone had something similar happen?!? Or could My body just still be "off" from
BC? Thanks!!!
