Got pregnant with IUD!!

So i got my paragard put in, in January. Last night I bought a pregnancy test because i was spotting for 2 weeks and no period.. To my surprise the pregnancy test came out positive!!! 😣😣 WTF!! I called my doctor first thing in the morning, and they were able to get me in asap! She did an ultrasound and did some blood tests to check my hcg levels. So turns out the paragard was ON MY CERVIX AND NOT ON MY UTERUS  LIKE IT WAS sopposed  TO!! 😡😭 In the ultrasound she was able to see a yolk sac and she said i was about 3 to 4 weeks pregnant!! She pulled out the IUD and said that it was more likely that it wasn't going to be a healthy pregnancy, and that there was a high risk I would misscarry .. She suggested id get an abortion.. Im so devastated! Im not ready for another child! My LO  is 4 months and i went through hell my whole pregnancy.. I ended up getting preclamssia when i was 7 months and baby was born early, I felt like i was going to die the last cuple months! Idk what to do! abortion sound horrible but i don't  want to have a baby right now!! I cant get the ultrasound image of the yolk sac out of my head, she said the sac was in the correct spot, but there was a high chance it was not going to be a good pregnancy! Idk what to do, what to think, or what else to say!! Im so heartbroken!! This would be my 4th child!! Wth!!! I was on birth control because I did not want more kids any time soon, and then this happens!! 😞😭😭😭 i feel like if i get an abortion i could never forgive myself!! 😢 but then my heart tells me it is the best thing to do! Idk i feel hopeless!! 😢 what if I let Mother Nature take its course, but what if the pregnancy goes smoothly and everything turns out good?? Id hate to interrupt my pregnancy if my body doesn't do it, then I'd be further along and I would end up feeling worse!! 😭😢 idk what to do! Anyone here been through the same situation??
