Don't feel pregnant

Lauren
Hey 
I don't know if I'm just panicking as I have previously suffered a missed miscarriage at 8 weeks, I'm now currently 15 weeks pregnant but I just don't feel pregnant feel completely normal havnt got a bump just bloating that's not hard or anything I can suck it in should I be worried at this stage and not seeing or feeling pregnant, boobs were sore but aren't now?
