Slight spotting

Mallory • Married 💍 and mom of 2. Have lost 3 in the past but hoping to give my husband a child of his own.

So I’m currently in cycle day 16. I took 100mg of clomid on days 3-7. The last 2-3 days I’ve been cramping, today more than ever, and I’ve had pinkish spotting. But now I’ve had this. Is this from ovulation or implantation??
