Start of a line?

AF is two days late. I’ve tested negative the past three days on FRER. Had to buy blue dyes because that’s all that was available

(I know.) Took this this AM with FMU. Look like the start of a line or a BFN?

UPDATE: Still no AF. Today’s tests look the same as yesterday. No progression of a line, just these shadows. So frustrating! I’ve bought more pink dyes and will test again with those in a couple days. 🤞 🤞 🙏🏻🙏🏻
