I could really use some advice.

I'm standing in my bathroom completely in shock. My partner and I just bd (for the 5th day in a row 😂🎉) and after I went to pee, ya know to prevent infection. When I wiped the fluid was light brown? I didn't think it could be implantation because it wasn't spontaneous bleeding or anything. Well, about twenty minutes later I went to the bathroom again, wiped, and saw this? I'm some where around 4-6 dpo and I am so confused. I've had what feels like mild cramps the last two days. My period is over a week away and have NEVER had spotting. What could this be?
