Light bleeding during ovulation?

So my husband and I had sex like 4 days ago. I had some light bleeding the next morning which has never happened in the 10 years we’ve been together. We had sex again the next night and it was super uncomfortable and slightly painful for me which I’ve also never experienced.

I didn’t bleed again for those next 2 days and then this morning I woke up and I’m spotting again. I’m a super regular person and I never spot between period or when I’m ovulating usually.

I started my period in the 6th and got over with on the 10th.

We had sex on the 17th then I had the spotting on the 18th. Then today, the 21st. The light blue is when I’m ovulating.

I just had my 2nd 4 months ago and now I’m freaked out that I could be pregnant. But it’s weird to me that the bleeding started right after I had sex.

Could it have been from rough sex? But that is still confusing why I bled 2 days after the fact. And it wasn’t really “rough sex”. It was the same as we always do lol

I’m freaking out 😩
