Not feeling pregnant anymore..

Tiffany • I`m 25 have 2 children already and really want another baby with my husband
So I will be 15 weeks tomorrow and the last couple of days I haven't felt pregnant at all except for the whole peeing constantly and wanting various types of food at once. But other then that I haven't felt tired or sluggish my stomach would tighten up on one side or the other when sitting down or laying flat but I haven't felt that on 2 days now kinda like the baby would get in a ball. I have yet to get morning sickness at all. I know glow says it's normal but I don't remember feeling like this with my first 2 kids... I go back to the Dr next Tuesday which by then I'll be 16 weeks and should be getting to find out what baby is...
