Which chart is correct!?

Premom and fertility friend are saying two different things 🙄 I started using premom because fertility friend honestly sucks when you aren’t paying for a membership. I feel like premom is correct because of how my opks were and the cramping and everything I experienced. I know my temp didn’t immediately spike but the weather is changing and we went from using AC to heat and a fan on us so I don’t think that’s helped my temps much 😂 what do you guys think!? I’m also worried because on the 15th my husband didn’t ‘finish’ because we were both worn out from having so much sex 😂 so that has me worried that we didn’t do it enough 😓
