I completely understand how you feel. My DH have been TTC for years and nothing, my SIL goes off BC in December and gets a BFP in January. I'm happy for them but also jealous. Its so unfair and she keeps joking about how quick it happened for them and here I plod along month after month, negative after negative. I don't understand why it has to be so easy for some yet so very hard for others. My MIL is the worst too, she blames me and says she doesn't understand my "priorities", apparently unexplained infertility is a choice I made. Had to delete my FB account because I couldn't handle any more sonogram and baby bump pics. Its hard enough to go through it but when your family and friends aren't supportive its even worse.
For the past 7 years, I've heard my MIL telling DH & I that we aren't having anymore kids, that I should be happy with what I have. I mean seriously? It's not that I'm not happy with what I have, I just want kids! I think she secretly blames me for my sons premature birth & complications........heck, I kinda blame myself too.
Last cycle the day I got AF (seriously within 30 minutes, no lie!) my SIL called DH to tell him she was pregnant with her 3rd. I cried for hours
We're not telling anyone that we are TTC. Honestly, I don't want to hear the nasty comments from the in laws
