Please someone help!

So I was initially 5 days late so I thought I started my period on Wednesday I haven’t taken a pregnancy test since the 11th but the last 4 days all I have had is brown spotting is this my period? Or should I take another test? It’s not getting heavier or anything, I do have some very mild cramps, I had sore boobs yesterday but it’s gone today

. I know I ovulated as I use the Clearblue advanced ovulation tests. Anyone have some advice? Also I did have very light spotting on the 4th/5th which I thought was implantation bleeding.
