One nurse I spoke to at my clinic said my OTD is 16 days after egg collection (not transfer). But then the next nurse told me 14 days after embryo transfer. The info sheet they gave me said 14 days post ET but didn't differentiate between 5-day transfers and 3-day transfers. So I have no idea what my OTD is. My clinic doesn't do bloods - just a HPT. And if it is negative then you just leave a message on their message bank with the result and stop the meds. There is no follow up appointment (or rather, they will schedule a follow up to discuss your treatment and next steps but have warned this will be 2 - 3 months down the line). If it is positive then they just book you in for a 7-week viability scan but don't see you before then.
I am feeling pretty down about all this and would love to stop the drugs asap if, as I am confident it will be, it's a BFN. I'm currently 11dp5dt and haven't tested yet. Today is 16 days post EC but 14 days post ET won't be until Sunday. All that said, I'm also dreading the test given how confident I am that it will be a BFN. The mere thought of it is making me feel quite nauseous!
