(UPDATE: BFP!) Anyone smell AF coming but still get bfp?

Ok, this is going to sound SO weird and TMI, but usually a day or two before I get my period I can kind of smell it coming on—like a blood or iron smell down there. I’m 12dpo and just smelled it again and wondering if this means I’m out for the month. Anyone have this as a normal pre-AF symptom but still get a BFP? Can’t bring myself to test yet under the circumstances. (Update, in case anyone is searching for this topic down the road: I did in fact still get a BFP on 13dpo, so it’s possible!)
