Nervous

Currently, I am 5 weeks and 2 days pregnant. I don't have any symptoms other than fatigue. I had a chemical pregnancy in April and am excited to have got many really dark BFPs over the past week and a half, but I'm just so nervous this one is going to end as well. It's all consuming. I'm not excited yet, as I've simply convinced myself this one won't stick.

I have no spotting, no cramping, nothing, so my feelings are not based on any concrete evidence. Yet, everytime I go to the bathroom I'm expecting the worst.

Has anyone else dealt with this nervousness? The nerves that something will go wrong just seem to consume every thought I have. Any tips? :(
