gone into panic mode 😭

Samantha
I've been sick with gastro for a few days now...
But... what has me panicking is the fact that I've lost 2kg and I haven't felt any movement for days now!
I had been feeling movement since about 15w, and now I'm 17+3 and nothing?! No bleeding or abnormal discharge, but my bump looks smaller? 
I'm back at dr today, but I'm dying on the inside with this strong feeling I've killed my baby 😭😭😭 I don't know what to do...
