I'm getting more worried each day as I am nearly 3 weeks late. I've already taken two pregnancy tests a couple of days ago and they both came up negative. There seems to be no sign of my period whatsoever and I don't know what else to do other than wait?😩😔 Also have been getting different discharge for like over a week now, first it was really light brown colour and now it's gone to a yellowish type colour, does this mean anything???
