So, I am 8 weeks today and I have had very few symptoms. Sometimes I feel symptoms and then they away. Right now, I feel nothing that I can easily distinguish as pregnancy symptoms. No boob ache, some food and smell aversions, very little nausea. Is this normal? I am supposed to hear the heartbeat tomorrow but I am so worried it won't be there based on my lack of symptoms.
I normally don't go out of my way to ask for reassurance but I could really use some because I am really nervous.

Eta: I am not spotting or bleeding.
