Welcome to HealthcareMagic forum
today is 26th so till date it should come positive if it is. but unfortunately its not. you has mild pink discharge meaning you skipped your period. just wait for 4 5 days for periods, if it doesnt appear just do final UPT, and if negative plz visit a doc to undergo USG and treat your cycles. very rarely UPt comes positive after 5 weeks.
another imp thing is , if you wanna conceive then its the right age to undergo full screening with a infertility
specialist. plz do not do late and start your efforts.
I hope I answered your query. Wish you good health.
