@Sar1010 lol I know I'm very confusing! I hadn't told people that I was pursuing surrogacy, but had done some back to back collection cycles at the start of last year, the surrogacy process was very long and complicated and so I kept pursuing my treatment, having immune tests and treatment, having fibroid surgery etc. Our surrogate then got pregnant at the same time as me with perfect betas, whereas mine doubled in the 3 day window rather than the 2 days, but I can see online that the 48 hour doubling is a bit old school and most places say 2-3 days is ok. And I mean how much can you be reassured by betas, every study outcome I saw had positive outcomes with our surrogates numbers and now that pregnancy is over and mine, as far as I'm aware, continues.
Tip for cyclogest, get some lube, I have had some rectal bleeding this cycle. I read the PR route leads to better blood levels and unlike the vaginal route the gunk won't come out on its own, so one less thing to worry about. I try and avoid passing for a couple of hours where possible, but I think 30 mins is usually enough time for absorption.
My vaginal probiotic opinion comes from two places, firstly my friends fertility specialist had her use a daily vaginal probiotic in her FET cycle, so I replicated this, my worry is with the transvaginal scans and I don't know what pH the lube they use is and the embryo catheter can move bacteria into the uterus, it seems a good idea to use the probiotics in the transfer. But like I said I didn't do them the day before and day of transfer, there's no reason for why I did this, I just thought probably best to have a break then. The second source is this research protocol which will put participants on vaginal probiotics in a transfer cycle and continue them twice a week until the 6-9 week ultrasound, I may be going over the board with daily but I figure it's best to be over cautious bmjopen.bmj.com/content/bmjopen/10/10/e035866.full.pdf
