The wait!!!

How do you all wait for your first appointment?! My doctor is making me wait until 8 weeks and I’m freaking out that I’m going to have a missed miscarriage and the baby won’t be growing. I have never been pregnant or had a miscarriage, but I’m really anxious after reading about so many while TTC (I actually regret downloading this app). I have very few symptoms: some “hangover” like queasiness in the mornings until I eat, mildly tender breasts, gassy, and really bloated. I’ve not had any spotting, and only very mild cramps, but that aren’t consistent and don’t last long at all.

Are there any symptoms that progesterone is low? If so, is 8 weeks too late to start progesterone supplements if they find something is off?
