Negative test after a faint positive

Heather

So yesterday about 3 ok I took a test as I was due my period and nothing came I had a weak positive done another one about 5am this morning and it’s negative 😔 I’ve been reading about evaporation lines but the positive result I had yesterday came up within a minute if not immediately where do I go from here? Been trying to conceive since my son was 1 he’s 5 now 😢
