Am I pregnant again or is this symptoms from my miscarriage?

[Xtarnix]

I miscarried on the 19th November I was 6+5 I had bleeding a little bit since the 14th but when I finally fully miscarried I only bled for three days is that normal? I had a scan on the 20th and the doctor said I had miscarried naturally and not to worry. About a week ago I started feeling sick a lot and sleeping all the time I wondered if I could be pregnant again? It's not exactly the same as last time I don't have sore boobs I took a test but it said negative so now I'm a little worried I could be the aftermath of the miscarriage? If anyone has any advice please because I'm really confused I can never get through to my doctor so do not know if I need to be seen or am just going crazy :-/

Forgot to add that I have been have lower abdominal pains also exactly like I did before not period pains but uncomfortable

I doubt you'll be pregnant again so soon you'll probably still have pregnancy hormones in your system after the miscarriage

Did you take a negative test? If so it's unlikely to be pregnancy - even at 6 weeks it can make your cycles weird and painful.
However if you're concerned ask for another scan - retained placenta can cause issues and infections but this is quite unusual and usually your hormones don't fall.
