I am 15 weeks pregnant and I have been feeling weird sensations for 7 weeks now. It feels like a tendon pops to the side or a fish flipping in my stomach and happens when I bend over or turn a certain way. I've been pregnant before and never felt this.

Sounds like the baby moving to me. I had that feeling when my son flipped. And also felt the tendon pop thing you described when I pulled something inside...

That's what it felt like when my little guys started doing flips for the first time. Some babies like to do flips more then they like to kick. I'm 7 months along with a "flipper" and now he's so big that when he flips, you can see his feet and his butt move across my belly! Good luck with your little "flipper!"

Ok I have to add that the popping is probably round ligament moving around. I had it with my twins and it will sometimes be painful. As for the flopping that's the baby moving. You typically notice it earlier with you second and subsequent pregnancies cause you know what to feel for.

I also had this feeling but it was after I had my son I would bend over to get him and this bad popping sensation in my side I would hurt so bad I haven't had one recently and I don't know what it is but I'm still alive and kicking
