Well @Sunshine015 did you read my post about our previous IVF? We have left 2 embryos in the freezer from 2 different embryo creation sessions. A day 5 they will always use first (so using on weds hopefully, we used the other day 5 from that round in feb, git BFP but resulted in early miscarriage). And a day 3 from another round. We used the other day 3 from that first round 3 years ago in a day 3 transfer to my best friend as a surrogate for us. We aren't told cells at day 3, just "it's doing ok & better inside a body than out". That day 3 is THE LOUDEST just over 2 year old healthy DS EVER who is currently upstairs snoozing. So it doesn't matter the cells, they have every chance. 🥰😘
@unknownscot id just go with it, it could be your body just getting used to it. If it continues I would phone your clinic x
