Bloody discharge

So I'm not on my period and it's been nearly 2 weeks since the end of my last period. I keep getting slight cramps in my stomach and when I wipe have browny bloody discharge, should I be concerned?

I've done the usual Google and worried myself.

Anyone else have this and it's turned out to be nothing?

My stomach really hurt after we had sex too the other day but I already had the discharge before that.
