A question about thermometers...
Ok I've been charting off and on for 5 years so you would think I'd know this answer, but I don't. My thermometer broke so I replaced it and started using it this morning. Could that affect my actual temp? Of course it had to break around O time. I'm having a lot of EWCM still today so I'm thinking I haven't o'd yet. Any insight is welcome. TIA.
