Am I having an emotional break?!

I don't know what it is about today but I all of the sudden feeling intensely worried that something is wrong. I feel like it might be because I told my co-workers this week so now it seems more real and that if something is wrong I have to share it everyone all over again. I was driving to work today and I caught myself having a daydream that we went to the 12 week appt and there was no heartbeat and I actually screamed out loud "No! No please no!" And started crying. I'm assuming it's also the hormones too as I've been crying at everything but I just can't help it. 3 weeks still seems so long and I feel like I'll feel better after the 12 week mark even if there is no guarantee. I wish I had more symptoms to keep my mind at ease as well. I'm sorry I'm probably all over the place right now and not even making sense. I just want to know my baby is okay and I just don't know if I could handle another miscarriage emotionally and mentally. 🙁
