19dpo and I’ve had a chemical pregnancy

Hey

Just wanted to let out some feelings I think, I love my partner but I don’t think he truly understands. I’ve been testing positive since 13dpo, took a digital at 16 DPO which told me I was pregnant 1-2 weeks and now my tests are coming out very very faint or negative (I took 2 brands)

I’m so upset and frustrated, I got so excited and now I just feel heartbroken.

I havent bled yet and just wanted to ask if any of you knew from experience how long it should take me to bleed?

Thank you
