Normal to feel "normal" at 15 weeks??

Lo

I'm 15 weeks tomorrow and for the past 2 weeks I've been feeling pretty normal. Less symptoms and no visible bump! Saw the baby at 12w2d with a strong heartbeat and all prenantal bloodwork came back normal! Also, no physical signs of MC. Sometimes I forget I'm even pregnant!! I've had 2 missed miscarriages in the past so I can't help but think the worst. Is this normal... can any other ladies relate?
