Feeling baby 11w4d

Hello! This is my first pregnancy (done via <a href="https://glowing.com/glow-fertility-program">IVF</a>) and this morning I woke up to the feeling of pop rocks going off down where my bladder is in my lower tummy (obviously not in my bladder). I’m also very thin. I was wondering if this could be baby! I’ve never felt this particular sensation before and I’ve felt quite a bit with IBS… could this be baby? We saw baby yesterday for my first OB appt and they were measuring right on track! So hoping to meet this little babe in Feb!
