PP Bleeding After Sex?

I’m almost 7 weeks pp now. I had bleeding after delivery until around 2 weeks ago and had brown spotting up until about a week ago, and haven’t noticed anything else since. But I just had sex again for the first time. It wasn’t painful or anything, but when I went to the bathroom shortly after, I wiped and noticed some pinkish-red spotting. I didn’t think much of it, but the day after, I had sex again, and the same thing happened. Is this normal? I was cleared for sex last week and like I said, it wasn’t painful
