Quite a bit of pink spotting in am?

I'm supposed to ovulate in 4 days, this morning I had pink spotting to the point it dripped quite a bit into the toilet and I wiped several times. Pink not red and I don't typically spot in between periods.

Now my husband and I did have quite a bit of sex the past 2 days since going a week without (long story we argueed lmao). I'm wondering if it's just some bleeding from that, but it's so faint.

Anyone have anything similar? I don't seem to ovulate the same time every month and I did notice more CM leading up to when we had sex but I don't think I saw EW texture. The one time I avtually got pregnant was a later ovulation and that's how mine seem to want to go.
