Lines aren’t progressing??

🌸

I posted this elsewhere sorry if you see it twice!

My AF was due on the 1st, usually right on time with very regular cycles (26-27 days consistently)

I took a FRER on the 1st and got a vvvfaint line. Since then, I have taken 3 more tests (Saturday <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>, Sunday morning and Sunday <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> - all are dollar store tests except FR) with the last longer pink and white one being this morning with FMU. I’m concerned I’m not seeing the line get any darker. With my first pregnancy I got a clear positive 3 days before AF and blazing dark lines 1 days after missed AF with FRER. I’m healthy, never experienced a Mc or chemical. I don’t know what to think - has this happened to anyone? Advice needed please 😓

Also I should add I’m not sure when I ovulated but suspected the 18th/19th and I only got to BD on the 18th (just once!!)
