Bleeding before expected period

Heidi

So I have pcos and my hubby and I have been ttc for almost a year. We did a round of clomid and I have spotted 3 times twice a few days after my ovulation and now 5 days before my expected period I'm spotting again but it's like a darker color not bright like my period blood... I'm trying to keep calm, but I googled it and it said it could be implantation bleeding, but it could just be period blood early? I'm wigging out!
