hi this is my first post here, im not the one that struggles with infertility but my sister does, she is six years older then me, she has PCOS and after recent tests has been told she has sticky blood, she conceived naturally once 7 years ago and sadly ended in miscarriage and she just had her fifth round of ivf, one was a chemical one was a molar pregnancy ( I have no idea what that is ) another miscarriage and two bfn's, the reason m posting is because I have two children aged 7 and 5 and she dotes on them, however im currently 18 weeks pregnant, I no I need to tell her but I no from experience with my son how much this will hurt her, she has been trying so long and would be a amazing mum and I just feel awful that its easy for me and she is having such a hard time to create a family, when I told he about my five year she broke down and didn't talk to me for a while ( I understand this ) and she found it so hard to cope especially after 2 weeks of telling her she had her first bfn and I had no idea what to say, I couldn't make it better, now with this pregnancy she had her chemical pregnancy just before I found out I was pregnant, I don't want to break her heart she means everything to me but its not like I can hide it forever, as you ladies no from your own experience how she feels can you help me please
