Positive test 4 weeks after d&c

katy 👼👼👶👼

I unfortunately had to have a d&c about 4 weeks ago. I was 11 weeks. I took a pregnancy test 2 days ago and it was positive. I think it is just left over from my previous pregnancy (although I hope I'm pregnant again) has anyone had this experience of still testing positive a month after a d&c? Going to see my ob today and I'll have a blood test done
