Is this pretty common/normal after BFP??

I just got my BFP 2 Days ago but last night and this morning I’ve had this brownish spotting only when i wipe. This is about the same amount everytime. I have a 6 & 7 year old and this never happened during my previous pregnancies so I’m kind of worried😰 Has this happened to anyone and you turned out having a healthy pregnancy/baby afterwards??
