Period no pregnancy

In January I went through a miscarriage. Bleeding lasted 7 days and then since that time nothing. I am 10 days late and never ever have I been this late. Seems like I will not get my period anytime soon.

I’ve took pregnancy tests, all negative. Just wondering if someone had this previously and what the outcome was?

I have exercised few weeks ago to just keep my mind off it and i am eating healthy. Rang doctors and said they can’t do anything until I miss my period for the next 3 - 6 months which I personally think 6 months is a long time. Doctor also said to keep an eye on it and do pregnancy test, but as far as I can imagine, if there’s no period no pregnancy can occur.

Can anyone help me please?
