Crying 😭

3 days until my period is due and I’m having symptoms I never experience before my period and still getting BFN… I’ve been having veins all over my chest and shoulders which I experienced with my rainbow baby, I’ve been extremely thirsty, napping everyday from being just extremely tired which I NEVER do, tender breasts, and had ovulation spotting and then about 2 weeks after we had sex I spotted again which I was thinking could be implantation spotting… 😕 how many days late should I test positive at the latest?
