Hi OP we initially went with the NHS. Did all the tests and found out I had multiple fibroids and a blocked tube. That was a low point, and then got given our next appointment with the hospital - seven months away! So decided to go private, and straight to IVF.
In terms of the process: I had to take a nasal spray for a week (IIRC it was to stop me ovulating naturally), which was horrible as it tasted like liquid Panadol. Then after that I started the injections. After a week of that, I started going to the clinic every two-three days where they would take bloods and monitor the growth of the eggs. Once they reached the right size, I was prepped for collection which was done under GA.
The next day we were told how many eggs had fertilised and then decide if we wanted them to go to the blastocyst stage or have them put back in on day 3.
Eggs being put back in was a breeze, no anaesthetic required (though you did have to have a half-full to fairly full bladder which was uncomfortable!). Once that's done it's the 2ww. At my clinic I was put on progesterone as soon as the transfer was done. Progesterone was very yucky, I've never ruined so many knickers in my life!
I've done two cycles - first time round had 7 eggs, 4 fertilised but only 2 were viable (but both were high quality embryos); second time round had 2 eggs, both fertilised and made it to blasto even though they were on lower quality compared to first time round.
I was OK throughout the process, was lucky enough not to experience mood swings etc, and we now have two lovely DDs (aged 4 and 2).
Fiestylittleowl I'm so sorry you feel that way. It's hard, isn't it. I felt a failure too as we'd been married for years (and both mum and MIL would ask "when are the grandchildren coming") before IVF. I think if I were in your position then I probably wouldn't say anything unless I was 100% certain she would be supportive - I didn't tell anyone when we did ours as didn't want any added pressure, and also like to keep things close to my chest in any case.
Good luck OP and all other ladies on this journey
