Total devastation yet again-but some advice?

Stephanie • Mummy to two beautiful little girls!

So I have a 28 day cycle but ovulate on day 18. I was due my period today but at 10dpo (yesterday) I had a faint line on FRER and on clearblue. I expected that I would bleed today, because this is now the 4th “chemical pregnancy” in a row so I’m far from optimistic whenever I see a line. But usually, as soon as I start bleeding and then test again they’re completely negative.

I followed the same cycle today, cried a little then took a test and I think the line is a bit darker? I know it doesn’t matter how dark the lines are etc I think I’m just clutching at straws and trying to find some comfort in others stories/experiences.
