Annie ~ I haven't gotten it yet. I just ordered it yesterday. I should get it this week. My MW was able to find baby's heartbeat with a doppler at 10w so I fully expect to be able to find it at 13+w. Like I said, I had one when I was pg with ds2 so I know how to use it. They are pretty easy. You can get one brand new off ebay for about $60.
I feel the same way. I keep measuring my belly. While I've gained about 2 inches since the beginning my belly hasn't grown any in the last few weeks. I also haven't gained any weight. If anything, I've lost a little bit. I'm assuming that's because I've been sick with a cold and haven't had much of an appetite. I haven't felt any of those fluttery movements in 4 or 5 days. It was my freak out over that that finally pushed me to just buy the darn doppler. I do think my uterus has grown. It seems to closer to my belly button. And when I first wake in the morning with a full bladder, I can feel a hard, little bump right below my belly button rather than just the overall bloated, fat looking belly. I can't see it, though.
I had ordered some low waist maternity pants from Old Navy that were recommended for the first and 2nd trimester. I got the same size as I normally wear because that's what they recommend. They were huge. I exchanged them for the next size down. Still way too big. I'm trying the next size down one more time and then I give up. The customer service rep I talked to about the sizing said that I just have just not gained as much weight as most pregnant women.
I haven't felt pregnant, either. It just occurred to me yesterday that might be because I stopped taking progesterone last Monday. Yesterday was my last day on metformin, too. Yay!
