Hi Ffion, Welcome to the community page.
I would say that what your are experiencing is completely normal when having treatment. It can be very uncomfortable but please let your clinic know you aren’t feeling great as their can be some complications like OHSS which is Ovarian Hyper stimulation syndrome where you over respond to the medication and that can make you feel bloated and, uncomfortable, breathless and sometimes difficulty when going to the toilet. It’s rare but it can happen so let your clinic know for sure.
I am sure some of the other members will reply with what their experience was like 🙂
Let us know how you get on.
