Is it possible?

Im 14+3 but when I got my last ultrasound baby was measuring ahead a few days, so i think i may be 15w. Anyways, last night i was laying in bed with my s.o and i'm about 90% sure I felt the baby roll over. It was sort of like a pressure feeling starting from my left side- to my right, and then it stopped after a few seconds. My boyfriend put his hand on my belly, and he said he felt something but its still early.. Have any of you ladies experienced this?!
