Hi mistymom! I currently use Ovia as I like their comparisons to different things like toys fruit etc. I also like their daily update on baby so today mind says that the placenta has now fully developed! I also use nurture which I like the pictures of baby as they don’t look as creepy as some others, additionally this ones good for tracking you taking your vitamin, weight symptoms etc.
The NHS also recommends you use bounty which I’ve downloaded but I don’t really use as I don’t find it as interesting!
