Babies everywhere...

After a year of TTC I got my BFP but had to have a D&C due to my progesterone levels dropping drastically. I was 7 weeks with my first pregnancy. I felt like my heart was ripped from my chest and now it feels like everyone and their brother is pregnant. I want to be happy for them but at the same time I wish that could be me. Has anyone else gone through anything similar? And if so how did you cope with it?
