Could it be?

So the app says that I’m now 10 days late for my period (was supposed to start 7/13). My cycle is extremely regular 28 days to the day. This past Friday I had some brown spotting (only when I wiped) for a couple of hours then nothing Saturday. Yesterday more very faint brownish spotting only when I wiped. My boobs have been incredibly painful and bouncing or rubbing and I feel like Satan is coming for me. I took a couple of hpt’s last Wednesday and nothing. Is it worth testing again ?
