I noticed that a few people were using the Ovia app so I thought I'd give it a go. I signed up and it gave me a fertility rating of 1.0. I'm so upset...I don't understand why my rating is sooo low. I wonder if it's my age. I'm not going to use it as it's already increased my anxiety massively! Has anyone else had a low fertility rating on there and does anyone know what on earth they base it on?
