I was pregnant for a week...

I was so happy when I got 3 BFP tests!!! We had been trying for almost 9 months and wasn't sure if we'd be able to conceive given we needed help with our first. But something didn't feel right, so I went in. She ordered blood tests to check the HCG levels. They went down. I took 3 more blood tests and it continued to drop. I was hoping I was wrong and I was worried over nothing but...now, as I'm miscarrying, a coworker announces her pregnancy. Trying not to be bitter but it's hard not to be sad. 😢 I guess I just needed to vent...
