Possible misscaridge advice

Sorry if this is posted in the wrong group didn’t know where to post!

So I basically was about 1-2 days late then I had my period, usually always quite heavy but this time it was light and today is my 10th day on the period, my breasts always hurt for a week before period but they were still hurting till this date so decided to take a pregnancy test today, and it was positive! But then I was abit worried because my bleeding that I thought was a really long period has started to get heavier slight pressure feeling but I’ve had no pain. I rung the doctor and he said I think you are having a misscaridge and to basically wait it out? I’m currently having mixed emotions I don’t know whether to be happy or sad, I just want to know if anyone’s had similar experiences and what happened.

Thank you for reading :)
