A faint line BFP on 3rd and AF spotting on 5th. Is it my period or just spotting?

Yamini

So I had tested with the First Signal on 3rd morning and got a faint line. Also have other symptoms like sore bbs and nausea and cramping. But today morning when I woke and peed I could see this brown discharge and when I tried to wipe with a tissue there was nothing!

Does this happen when you’re pregnant?
