I don't know why but I have been worring that my IUI was with the wrong sperm. The clinic I went to is a fertility center but also a sperm bank. The nurse was late and rushed and I am just so worried she grabbed the wrong vial. I think I am worried becasue this is the first time I have not been with DH goods threw the whole experince. ugh I am sure everything is fine I just cant shake the haunting fear. 

Doesn't Ericsson do the swim up or whatever in front of you?  I've heard people can watch while the nurse does the stuff with the sperms...

 no it was around a four or five hour process. I was going to see if DH would stay with his men but desided not to be a PITA lol. 

OMG.  If you even have the slightest fear, sweetie you should go get a paternity test and if it turns out that your fears are real, sue the pants off that clinic!!  WOW.  Does your DH worry or have you mentioned it to him?  This is a huge thing to have on your mind!  Call the clinic, talk with DH.  They can do tests while your pregnant these days I think.  Bless your heart.  You may be worrying for nothing, but if it's entered your mind, you will always "wonder".  If you can live with that, leave it be, if not, do your checking up and see what you find out. 

big hugs and I hopw it all works out.  I could not imagine the worry.
