Frustrated..

So i am 28yrs old. Been ttc for a while now. I have a 19mo old and we want another one however I have PCOS and having a hard time concieving now, even with femara. We dont know why. I concieved my 1st same cycle I took Femara, now idk why Its not happening 😞I had HSG test & endosee this week. Everything was great.. im just ready to get pregnant, have this baby.. Me & hubby talked about it and this will probably be our last baby bc we are both just worn out.. We wanted 3 or 4 babies in the beginning but seeing how hard it was to concieve and all the stress we went through, we decided we would have one more so my son can have a sibling, but thats it.. Anyone else have a hard time concieving with PCOS?
