What are the chances...?

So I had two failed IUIs back in the fall 2017. Hubs and I have been trying for three years. Nothing. No miscarriage, nothing. We have unexplained infertility. I have insulin resistance and Hubs had low sperm morphology. But nothing that makes it impossible. That being said...

I scheduled a consult with my doc to look into IVF. It’s time and we’re ready. I scheduled it for tomorrow. Today marks me officially one day late for AF. What are the freaking chances that I would actually be preggo?! I haven’t been a day late since I got on metformin 2.5 years ago! I’ve always starting spotting a day or two before official period. And now, nothing!!

Don’t get me wrong, I am NOT complaining!! But geez of all the luck! I did POAS two days ago and got a BFN but it may have been too soon. Also my resting heart rate has been increasing pretty consistently. I’m still going to go to my consultation obviously but I’m just flabbergasted at this situation!

Any thoughts? Lol
