Before I start, Im going to give you a bit of a background
Im a single mother of 3 beautiful children. I just started a new relationship that I am VERY happy in.
I had a tubal done with my last pregnancy.

Well last night, I had a dream that I took a pregnancy test and it came out positive. I remember saying "This is crazy, this cant be happening....." I was really happy about it tho.
I can only remember the "special" moments in pregnancy, like watching my belly when the baby moved or feeling it kick.
Then I was in labor, screaming and crying in pain with many people around me (they werent my family) and they didnt look like doctors and nurses. Then a man with a mask handed me a pink blanket and in it was the cutest little face ever.

It was quiet vivid and it was almost like I was watching a movie of myself, but more realistic

Babies in dreams are often symbolic. In this case, the new baby, especially given your circumstances, is the new relationship in your life. Here's a link to the definitions of the symbols in your dream that will add additional perspective:

Congratulations on your new relationship. May your baby grow healthy and strong.

Your dream is beautiful... I am new to "dream interpretation" so unfortunately that is all I can offer you, that and I have had similar dreams in the past few months. I have had close to twenty dreams of either me pregnant, me holding my newborn baby, me with my adolescent child, etc. I was pregnant (in real life) but then was under the impression that I miscarried, and didn't have any more baby dreams, until a few weeks ago I had a dream I went to my doctor and he told me, "I think you are still pregnant." and then I had another one a few days ago where I went to the doctors and they suspected I was still pregnant. Can this mean that I actually might still be pregnant? I never had baby dreams before these last few months and it did coincide with me actually being pregnant.
