I had a HCG trigger on May 23d.. Probably ovulated on Sunday May 25th. We were supposed to have an IUI but that didn't work out so be BD Monday and Tuesday. Right now I am 9 DPO/CD 25. When should I go back to the RE for testing? What would they test for? This is all bearing that I don't get AF...... My RE is Dr. Brenner.....
