NEED HELP!!!

Ok ladies so I had a D&C done on April 25, 2019. I had a really light period 2 weeks ago. I believe I ovulated on the 17th of May (I felt ovulation pain)

A couple of days ago I felt like throwing up when I brushed my teeth, which happens to me when I’m pregnant. And today I bought a pregnancy test and it’s positive. I know HCG levels can stay in your body for awhile. But it’s been a little over a month since my D&C.

Had this happened to anyone before?

How long did y’all test positive after your D&C?

Did anyone conceive within a month of D&C?
