Girls! My 3rd pregnancy, currently on labetabol and aspirin for my blood pressure which seems to working perfectly thank god!

But anyways recently I'm not feeling so pregnant at all and I'm nearly 17 weeks(on Monday) I was feeling slight butterflies ish I think but no real movements as of yet.. is this normal? I can't really remember in my other pregnancies, also I'm quite a big girl so won't show for a long time anyways.. but I keep thinking is baby okay ect😩🙈
