Can someone help me?! Sorry long read..

So I found out I was pregnant last Wednesday lots of BFP's and have continued doing them since to watch the line progression.. then Sunday we did another couple of tests and they were negative and then yesterday again negative not even a faint line (I'm test mad). I've got 2 children currently so I know the line shouldn't have just gone. I'm so worried it's a chemical pregnancy as I would only be 4w6d today.

However now my tests are negative I've had a few cramps but no bleeding.

How long should I be waiting to start bleeding considering I'm now 1 week late and it's the third day since my first negative test?

I also didn't realise HCG could basically drop to nothing over night?

My DR has been horrible and useless so I'm getting no professional advice. He's just said retest Friday and it will probably be positive! (Why tell me that) They have said they won't do a blood test either because there's nothing that could be done if I am having a CP (which I know) it's more for peace of mind. To top it off the midwives have said to go to my DR.

Can someone please advise me 😔 I'm just lost 💔
