Miscarriage 7 weeks ago. Pregnant again at 4 weeks. I need advice x

[stazzminibbz]

I had a miscarriage 7 weeks 2 days ago now. Got my af 20 days later. And am now 4 weeks pregnant again. Problem I am bleeding quite heavily.. Just a tad lighter than my usual af. Been bleeding for 6 days now and been having positive tests for 3 or 4 days except Im not due my period for another 2 days yet! So.. Went to see the doctor who has told me this is a chemical pregnancy and I should pass the 'products' in the next week or so but to class it as my normal period and not a miscarriage. I want to cry. Anyway I got told by a friend of mine that my tests should not be getting stronger if I was about to have a chem! Please someone help me or share ur experiences with me I will upload pics of all hpts inamin thanks x
