Ugh bbt

Stacy • Sat, Nov 29

My bbt chart doesn't look good. I'm 6dpo and my temps have dropped below my coverline twice. I'm thinking it could be that the room was colder than my room's normal temp (we were visiting family). I'm just hoping it's not Lutheal Phase Defect. Anybody have this happen to them ever and still had a bfp?
