What finally worked for you please!?

Kassidy
I'm pretty desperate over here ladies and starting to give up :( I have a 3 year old daughter and lost my twins and had to have a dnc back in June 2014.... Been trying so hard to get pregnant since.. Been over a year and a half now 
I've gone to the dr had a hsg done and everything is coming back normal and all good
My dr wants to do surgery now for another dnc and to just look around in there
I was so hoping to get pregnant alone :( I feel so sad!
I've tried pressed but no luck 
What finally worked for you!??? Please anything helps
