No bump at 8 weeks

Is it normal to have no bump or bloating at all at 8 weeks? All the nauseas (I don’t throw up but I have no appetite + strong food aversion) probably caused me lose some weight and I’m naturally petite already. I saw some online pics people showing their tiny bump at 8 weeks. I don’t feel anything at all my tummy is still very flat. My baby had a good heartbeat when I went in on 6 weeks and 4 days. But my next apt is not gon be until the end of this month, I’m concerned my baby is not growing. Mommies and mommytobe if yall can just tell me what do yall think... also My husband and I both think I might be experiencing prenatal depression, since I found out I was pregnant I feel like I’m living with paranoia and anxiety everyday, this is really hurting my mental...I been crying everyday and stressing a lot.
