So...among other things:
You are put on an artifically induced menopause to bring your body to a neutral state before they fire up the fertility, so they can control it. So that's a mini menopause with papery skin, saggy jowels, swollen belly every time you do it.
You have emotional swings due to hormone spikes.
You have to inject yourself every day for weeks.
It costs a fortune.
All around you people are getting pregnant through having sexm which is a whole lot more fun. And free.
It costs a fortune.
You have to keep getting time off work for appointments, so people start to think of you as flaky.
Yoru partner never quite understands what you are enduring. I nearly divorced mine when he said he might not turn up to the egg collection - a long and painful procedure. And when he bought himself a big steaming coffee on the way to hospital on a freezing day when I was having yet another jeffing procedure and nil by mouth due to him being infertile.
You have to keep opening your legs to have total strangers poke around in there. For me this was absolutely the worst aspect. It felt like a violation.
And after all this, you get a dull back ache and a bleed. So all those missed nights out because you were injecting, and sore bruised legs, bums, stomachs from injecting and all those thousands of pounds, and all those mood swings and rows and shreds of hope have to be relived all over again for the next cycle. meanwhile the news always seems to be full of people horrifically abusing their natural born childrena nd you just want to scream at the injustice.
But apart from that it's not gruelling at all! 😀
