Hey Pummalaemma
HI!!!! Thanks and Congrats to you too!!!
When I got it I said I would only use it until 4 months, just enough to get me past the first trimester. But I just love it so much that I may talk to DH to agreee to keep it till the end....but we'll see. I realy love it! I wil just change my plan if I do so its a little cheaper
I started using mine I think at just 10 weeks ......the heartbeats were harder to find then...but now at 15 weeks its very easy. You just have to be very patient when looking for he heartbeat...you have to glide very slowly because these mahicnes are very sensitive. It took my DH about 30 minutes to find one of the heartbeats the first time we did it....Lucklily hes very patient cause I started to freak out

oh and the first time I found our babies they were both just above my pubic hairline, right above eachother....sorry TMI, but it was allot lower than I thought
Anyway I opted for the model with no bells and whistles, and also the month to month plan

But there are many options to choose from.
