I've been taking my ovulation test all week,and according to this app and 2 others,I should be,but my test show that I'm not. Any ideas? I've never done this before with my first son we werent trying nor preventing so I'm kinda new to all this and learning about it all. Any thoughts? I had an IUD for 7 years and just had it removed end of February and started my period on the 27th. Any thoughts would be greatly appreciated!
