First time doing this- please help

A

I am doing my first round of <a href="https://glowing.com/glow-fertility-program">IVF</a> and yesterday was told that I have 16 follicles that are fairly large in size. I am due to trigger on Saturday and collection Monday but I’m worried about OHSS.

I am extremely bloated, I have stomach cramps, back ache and I couldn’t sleep a drop last night as I felt like I couldn’t breathe..

Can anyone tell me what the symptoms of OHSS is or if this is all normal? Thank you
