I had my HCG shot on 7/29 and I started testing 2 days after (the day I have my IUI on 7/31). I have been testing every morning pregnancy and OPK. I want to test the pregnancy line out so I know when I test for real if I get a line its mine. My pregnancy tests have faded like they should but the OPKs have stayed position. I have included a picture. I do have PCOS but I have tested after IUI last time and it didn't stay positive like this. Any ideas or suggestions?
