Help needed.....so confused

So i have been on fertilaid the last 2 months to help regulate my cycle as it was around 42'days. The last two cycles it was 32 and 33 days which was great.
​Day 32 of cycle was Tuesday and I was expecting af on Wednesday. I have now had brown spotting everyday since Thursday but just a small amount. glow predicts af for Friday next week based on my 42 day cycles I had had.
​Is it to early for a bfp? Could it even be that?  Any help would be great guys. Thank you
