I'm 18 weeks today. And I've felt little wiggling movements the last two weeks, but I'd always check with a Doppler as id be unsure.
But I'm more confident that the movements now are baby, especially today.
I listened in on him for a bit and I felt him prod the Doppler a few times.
Then after when I was just laying down, I felt four prods (the hardest yet!) immediately got my other half to put his hand on the same spot and wait and he felt a couple of small prods (they would have been quite strong prods for baby but it's not very noticeable from the outside) and he felt a weird bubble popping and wiggling sensation.
I can't wait to feel more prominent movements!
