I have posterior placenta previa, 23 weeks. I feel some really big movements, but still go several hours without any. They wake me up in the morning, I feel them in the evening such as when I go to bed. During the day the more active I am the less I feel, I think if I'm walking around a lot the rocking motion sends it to sleep! If I'm sat and the desk touches my stomach or I have my laptop or a plate on it baby wakes up and kicks it until I remove it, or if I'm hunched forwards it isn't shy of giving me a boot to remind me to give it more space 🤣.
Some days I feel huge amount of movement, sort of like its going around like a pinball machine, other days I've been active and I'll not feel it for several hours, nothing when I eat or drink, tell my DH I haven't felt it and I'm getting worried, he touches my bump and talks to it and suddenly its all "Daddy's here, hello" and wriggling away!
