Mommas: how far along were you when you felt movement for the first time?

I am 20 weeks this Sunday. I went from feeling butterflies all the time to nothing. And I still haven’t felt actual movement. Had my ultrasound a week ago and they said he is okay. He’s breech but they didn’t seem to worried. The last two days I’ve felt a lot of pain in my pelvic area.. could it be because he’s breech? I just want to feel my baby :(
