Hello,
I just wanted to pass on my experience in the hope it helps others out.
I was at risk of OHSS due to high AMH (58) high follicle count on prior scans (avg 14), low weight and lower age (for ivf).
When I did my cycle, I did a short protocol, I had over 40 follicles and was extremely bloated but the nhs still gave me Gonsai 5000 (they shouldn't have).
I ended up with over 25 eggs and OHSS, where I struggled to walk and my stomach quickly swollen after egg collection. This did start to go down, so they still did a fresh 7 day transfer (again, they shouldn't have)
I did get a BFP but I ended up with severe OHSS, I got to the point I couldn't breathe, my stomach was extended as far as possible filled with Fluid and I was hospitalised for over a month, on drips and being monitored. Honestly it was absolutely horrendously, I've never felt discomfort like it. And it continued until I was 12 weeks pregnant as it's the HCG that makes OHSS worse, this does not stop doubling until the placenta takes over at 12 weeks. I missed months of work, I was in agony for the whole first trimester and it was throughly miserable, to the point I was crying for it to be over every day. I was having my urine output and liquid input measured, as well as my stomach measured like a turkey each day.
Obviously it's hard to say I wish I'd have pushed for a frozen cycle instead because it did actually work and I am grateful, however if I'd have researched properly back then and understood how bad OHSS can be I'd have definitely have pushed them to give me an alternative trigger and probably a frozen cycle so my body could recover.
The OHSS has caused complications to my pregnancy in that I now need to take daily blood thinning injections, and I'm at a higher risk of pre term birth, all of this could have been avoided with a frozen cycle.
Good luck for you cycle! I have everything crossed it works and you don't have to suffer OHSS.
