PIO Shots

I’m at the end of my TWW and have bloodwork tomorrow. I found out last night that we have been using the wrong size needle for the PIO. CVS send me 0.5 inch needles, which I began using before the transfer as instructed. CVS wasn’t able to ship me the next vial in time so I got a vial and needles at a local pharmacy. This pharmacy gave me 1 and 1.5 inch needles. I messaged the clinic and they said I should be using the 1.5 inch needle and completely ignored my question asking if the 0.5 inch would have a negative effect on the transfer.

I had some faint lines on at home tests but also took an ovidrel trigger on the day of transfer. The line on test this morning was more faint than before. I’m so disappointed that it could be due to the wrong needle size. We only have 2 normal embryos after 3 retrievals and this transfer used one. The other one is lower quality and doc doesn’t want to transfer it by itself.

Has anyone else gone through something similar with the needle size?
