Spotting Help😭

So I got a positive LH surge on Saturday, have been tracking my temps and think I might’ve ovulated Monday or Tuesday, and have been feeling a twinge of pain in my lower side. Last night my husband and I were BDing and when we finished I had a light pink spotting situation going on. My period is 11 days away and I don’t think it’s implantation bleeding. Could it be ovulation bleeding even though I haven’t had a positive opk since Saturday? Bleeding is gone this morning. All sorts of confused. Here is my bbt chart!
