Sweetpea - no, sadly I didn't feel at all better after I got a positive because I've had a previous loss and was convinced I'd lose this one too. I think when you've struggled with infertility for years and years and years, you get used to disappointment, so I just couldn't believe my luck and thought it was some sort of soon-to-be-rectified mistake.
I couldn't formulate a plan b whilst I was in the middle of ivf. I had no idea how physically or emotionally demanding the cycle was going to be and I'd no idea how I was going to feel about it coming out the other side. If the cycle had failed, I'd have needed time afterwards to re-evaluate, reflect and think about whether or not I had it in me to go through it again (the answer to that by the way is no - knowing what I know post-ivf, due to the emotional strain, once was enough for me even if it hadn't worked).
What we did do though was plan lots of fun things in case it was unsuccessful. We'd planned time off work, and had picked out an amazing holiday to Japan, China and South Korea. I'd found some fantastic Jimmy Choos, and a beautiful dress I wanted. We researched Michelin starred restaurants, and some spa hotels on the coast. It sounds very frivolous, but it distracted me and gave me other things to think about. I watched a lot of comedy DVDs, bought a colouring book for grown-ups, stocked up on books by my favourite author and marathon watched Breaking Bad too.
One thing I do know for sure though - don't test early :)
