Is it possible?

Is it possible to still be pregnant with the same fetus if say, 
I got a abortion (don't judge please) back in March of 2016 in the beginning of march with my exs baby. Afterwards never got my period and never went back to get a check up. It was surgical abortion done at 6 weeks. 
Well I met someone who is simply amazing and treats me oh so good that April. Well...... I got pregnant - don't forget I never got my period after that last abortion. Anyways went to the doctor and said that I conceived around May 8-11th and baby is due in January 2017... 
Basically what I'm asking is, 
Is it possible that I'm pregnant with that same fetus?!?!?!??
Please help and don't judge ...
And no I wouldn't get another abortion.
Thank you
