Swollen vag walls and super faint BFP? TMI

Zhenia

Last night and today I noticed my vaginal walls are swollen and spongy. No pain,no weird discharge. I’ve taken several pregnancy strip test which were bfn and only today saw the where the first line was after I peed on strip. Is this a possible faint positive? So confused and scared to be hopeful after a loss a couple of months ago.
