Okay, I'm 15 weeks and having my once weekly paranoid 'have I damaged my baby' moment.
Today I went on a trampoline with my niece. I sat on it while she bounced and I was challenging her to do different tricks like twirl around, bounce on her bottom etc. so as a result I was being bounced around in my sitting position. And a few times I kind of jumped up and down (on my bottom) just so my niece jumped higher (she's tiny, and I'm heavy, it doesn't take much!).
After maybe 10 minutes I got off and told her it was too bouncy for the baby.
And then I thought "oh god, what if it WAS too bouncy for my baby??"
Could I have detached the placenta? If I had done this, would I be aware of it by now? Could I have jiggled the baby about too much and shook it's brain?
I have a Doppler, but as it's 2.47am I might wake up DP who is a v.light sleeper.
Might go in the spare room and use it.
