Everyone is pregnant and I want one so bad!

Just looking to vent and not feel so alone. We've been trying for about 7 months now and it is so frustrating! My sister just had twins and I have to go visit her and be happy for her but it's hard not to be jealous. Plus I swore I was pregnant about a month ago. Had brown spotting a week before AF was due and then missed my period. Had a bunch of pregnancy symptoms but negative tests. I was still so convinced I was pregnant until I got an ultrasound that confirmed I wasn't. Finally got my period after being 57 days late. Now I have to go hold newborns after this disappointing pregnancy 'scare'. my coworker is also preggers and she is starting to show. This kills me!

We've decided to step up our game and I'm temping along with taking OPKs. He is taking preconception vitamins and I'm taking prenatals. also trying preseed.
