Still confused...

i am still confused.. as if the IUI and the crazy O size weren't enough.. now that i am back to the BBT thing.. i can't decipher my O date with ne certainty. i could've possibly O'd around the IUI or a week later. i have very clear thermal shift a week after the IUI but only a slight shift directly following the IUI. so while the blatantly clear shift could be a triphasic shift it could also be the original O shift..ughhh... neway i plan on testing this weekend - Saturday the 13th, and no matter the results getting a blood test on the monday the 15th at the RE's office (i have an appt on the 15th to discuss our next phase neway). the drama continues!!
