Brown spotting

So I just got my BFP today and yesterday I had brown spotting only when I wiped, as I was about to go to bed I saw it had turned a dark pink. I had sex with my SO thinking it was my period and that would just start it but this morning it's back to creamy cm and a BFP!! Is the brown/red spotting normal where it was only a day or should I be worried.
