I'm glad your son made you feel a bit better! Where are you going on holiday??
To be honest I was surprised at how low the success rates were for IUI -- 20% ish, not that much higher than just DTD. If you're young and healthy your success rates for IVF should be close to 50%. I'm not trying to sell IVF (!), and I know you're not keen on lots of drugs, but that was what I considered when choosing to go the IVF route.
Again, I'm so sorry you've had to go through this again -- BFNs are the worst. I hope you start recovering from your cold soon too. Xoxo
