Anterior placenta

I’m currently pregnant with twins and both have anterior placentas, I’m 16 weeks 3 days. I’ve been feeling a fullness/pressure when they move for about two weeks now. But nothing more than that. My stomach will get hard and I’ll feel pressure and when they stop moving it relaxes again. I was told around 18 weeks I might feel movement at the sides or bottom of my stomach. Hopefully that helps a bit!

I had an anterior with my Daughter, I felt flutters around 18/20 weeks and fuller movement closer to 24 weeks. More pressure than anything and felt the most movement on the left and right sides.

With my first pregnancy, I had an anterior placenta and started to feel movement at 19 weeks

I had an anterior placenta with my first and I felt her move around 20 or 21 weeks!

I have two anterior placentas currently( twins). All my singletons have had posterior placentas, so I don't have much experience with it yet. I've felt flutters here and there so far.
