Sad Day

So I've been a type 2 for almost 5 years now, and I quit taking my medication a few years back cause they were making me crash and my fr wouldn't change the prescription.. Well we've been trying to conceive for 4 years now. And I'm 2 months late so I went the the dr cause I've been having a lot of BFNs well I'm not pregnant. And my dr said I won't be able to conceive till my levels are back under control. I'm so upset.. It's all my fault were not having another baby yet..
