Spotting during fertile week.

I’m now on day 3 of spotting brown during my fertile week. Its a good amount of it too. This has never happened to me before is it normal to spot this much during ovulation time? I also am feeling a little sick today but that can be normal with ovulation for me. Also I just had a chemical pregnancy cycle before last so I don’t know if that could affect anything, my previous cycle the month after my chemical was very very heavy.
