Sorry to hear about your loss. After my first mc it took another 15 months for me to fall pregnant again. I lost that one too and started fertility treatment after that, even with treatment it was another 10 months. It is classed as normal to take up to 12 cycles, if it is taking you longer then you can go for tests to see if there is an issue that is stopping you. It is disheartening but stay positive, do what you can to maximise your chances and try not to let it consume your life (which I know is near impossible, but stay busy and keep enjoying life in the meantime).
