It's hard isn't it.
Even though they are our mums, I don't think my mum actually understands. She always asks why we aren't trying harder naturally...I've been seeing my FS for 7 years and only have 1 child (he took 3 years!). And even now, 2.5 years ttc again, she just really doesn't get it.

Try not to let it get to you. I honestly think that unless you've been through infertility and AC, as much as you want to understand or are empathetic, it's hard to understand.
