Thank you very much! It feels really nice to know that...
Not really. A few days after your IUI is too early to feel pregnancy symptoms, as it takes about a week before the fertilized egg starts to implant into the uterus. And it's after implantation starts that your hormone levels will begin to rise and you may or may not start to get pregnancy symptoms (some won't have any symptoms until well after their positive pregnancy test). Best of luck!
