Miracle???

I’m so very confused I honestly don’t understand how it’s possible. I had a stillbirth two weeks ago. The baby died two weeks before that but we had no clue. So for a almost a month I had dead baby in me because I missed appointments due to scheduling conflicts. So nobody knew and we had no complications or signs before. So it was shocking. But anyway I haven’t been feeling well, and someone was trying to be positive and say I was pregnant. I was more annoyed because I’m like not possible. I went to the doctor yesterday and told her how I felt and I felt crazy because I almost felt pregnant?? Turns out I’m Pregnant!?!?!?!? She told me I’m a month pregnant and I don’t know how that’s possible. She said that my body might of started ovulating as soon as I lost the baby. I’m just really puzzled and I’m confused and I don’t know if anyone has even been through this? How can I get pregnant while pregnant? My doctor checked and confirmed it..
