Heavy mid-cycle bleeding

Has anybody ever had heavier mid cycle spotting or ovulation bleeding before? I had a chemical/early mc last cycle that ended at 4w4d and I’ve been done bleeding for over a week and my hcg is back to 0. I’m CD (cycle day) 13 today, had a flashing smiley on a clearblue digital yesterday but my ovulation strips are still negative. I had a tiny bit of spotting yesterday but only when I wiped. But today it’s more of a red and although still technically spotting it’s every time I wipe and a bit heavier. Is there a chance this is ovulation bleeding? It is it too heavy? Is it possible I’m just going to start a period-like bleed 2 weeks after a chemical?
