Tomorrow is the beginning of week 21.
Aww, poor DH.
That's awesome that you are feeling movement!
Yes, the first time I felt the rolling I thought something was wrong so I really paid attention. The best way I can describe it is for you to make a fist, put it on your belly with your folded up fingers touching your belly and slowly lift up your wrist. It feels like that just with a bit more force. LOL, I don't really know of that is Monkey rolling but every time it happens that's what I picture.
I started trying to hear the hb with a stethoscope weeks ago and have yet to hear it. In one of my books it says that even practiced OBs have trouble hearing the hb this way. I might try again, but like you I only hear my hb. Since mine is faint I imagine Monkey's hb would be difficult to hear anyway.
Yay! I love being able to feel their kicks, it is so exciting,
