So after a long 13 months of ttc for our second, my husband and I have decided to go through with <a href="https://glowing.com/glow-fertility-program">IVF</a>. It took us 2 years and multiple rounds of treatments with our first and after 3 follicular ultrasounds and blood test we can see that my body isn't ovulating. So today we told my family our decision (only bc we all live together) and no one had anything good to say. I'm not one that needs people to be happy for me but it would be nice to have their support. I mean the ONLY reason we decided to rent a house and move them all in was to support my dad through prostate cancer. I didn't make this choice lightly and would love to not have to go through the meds and the stress but I would love to have another child more. On top of that I would love to be able to take care of my PCOS and not be in pain any longer! Why is it that just those to reasons aren't enough to just be happy for me??? 
I know this is just venting but it just sucks.... 😒😒
