Im sorry to tell you but you can get pregnant with an iud I recommend you see a dr adap and yes you can have the baby but you may have complications best wishes.
I am having all the symptoms I was having last time.
It is possible, but chances are slim. If it's been 2-3 weeks since intercourse then it would show up on a home pregnancy if you were pregnant. No, you don't need to have an abortion just because you have the IUD, however, you get pregnant with it in, chances are slightly higher for ectopic pregnancy.
What makes you think you're pregnant?
