I masturbated early this morning (2ish am)

But early this morning (3am) when I went to the toilet and wiped there was a little pinkish/reddish blood. Nothing too alarming.

Now when I went to the toilet and wiped, it's brown blood and a fair amount too.

I was getting one brown blood clot (only small) 2x when I went to the toilet.

Now the brown discharge has reduced dramatically and nearly gone

Should I be concerned?
