Don’t even feel pregnant and I’m scared

Erika

So this is my 3 pregnancy, I had a miscarriage last year very early. So this one I am very very nervous . I am 17 weeks and 3 days . I haven’t felt him move , and I just don’t even feel pregnant and I’m getting very scared. My last app was beginning of September and heartbeat was strong . I don’t no why I feel like this. I have a small belly sometimes I’m popping more then other days . I hate feeling this way and being so nervous . Is anyone else feeling like this ?
