17 weeks, 3rd pregnancy and no movements?

I'm 17 and 4 and honestly my belly feels less pregnant and I'm not feeling any movement. I guess I was very bloated before but the baby was very active at our first scan and not being able to feel anything makes me very nervous.

Apart from the lack of period and occasional discomfort when I bend over I don't feel pregnant at all.

I'm heavier than I was with my first two, will the extra weight make it harder to feel movement? I thought I was feeling movement a couple of weeks ago but now I'm not sure.

I feel like I imagined the whole thing. We've had a scan, I've seen the baby. But everything seems so absent that I have started to feel like I imagined it.
