3 days late BFN

RiRi • 🌷💟🌷
Hey ladies I could really use some advise. My period is always on time if not its a day early or a day late. I've been ttc my rainbow for over a year. I'm 3 days late and I have taken a pink dye test yesterday afternoon and a first response test using fmu today and both negative. Anyone experienced this and got a bfp what's your experiences. Thank you ladies
