HELP!!!! Ok so I know FF has O day wrong. I know I O'd cd28 but FF keeps flip flopping my days every day. As most of u know my bbt thermometer went out so I have a few days not logged (hence dotted crosshairs) however, I haven't started my period and after my huge dip which is usually AF day she didn't come yesterday. Today I have a slight increase. I'm so confused. Am I missing something? Maybe actual ODay later? I really don't feel any other day works as far as symptoms and tests. Except last night I had a positive OPK.
