@Tanith thank you! Is it free?
Preggers! It’s brilliant x
Femometer
@Jennie it's free but they have a premium option too
I use Flo. Premium version costs ~20-30£ per year. There is a free version also.
Emmas diary is free
I use a few. Pregnancy+, Preggers and What To Expect are my main ones. This app does it as well. Then I have Bounty, Baby Center and Emma’s Diary for other info, offers etc
Pregnancy+ is good and this app has a tracking feature
